my windows application crashing frequently on startup - windows

I am trying to develop an application on windows 10 in Flutter 2.x.x. I am implementing bluetooth functionality with the app. The problem is that application is mostly crashing on startup. It is working only once I tried several times after it crashes.
The error message is just Lost connection to device.
Could you help me on it?

Electron Debugging

I have an Electron app in the Mac AppStore that is essentially just a wrapper around a hosted web app. A few months ago one specific thing has stopped working in this app. I'm using redux-offline to sync changes to the server and this is just not happening any more.
It's working when running it outside of Electron - in any modern browser.
All other requests are working fine.
It's working when debugging it locally.
It's working when running the built version locally.
BUT it fails in the published Mac App Store version. I'm not catching any errors in my logs (server-side or client-side). I just upgraded to the latest Electron (electron#4.1.4, electron-packager#13.1.1) hoping it would solve it - to no avail. I don't even know how to properly debug it since it's only failing in the published version.
Any ideas? On causes, solutions or ways to debug it?
Seems like your application closes by itself. Check all of app.quit executions. For me issue was that app.requestSingleInstanceLock() returns the wrong value for Mac Store build. Please check this issue, if the problem is related to app.requestSingleInstanceLock().

Flash Builder failed to connect to running application

In Flash Builder 4.7 i get the following error message
The Flash Builder debugger failed to connect to the running application.
Ensure that:
For in-browser applications, you are running the debugger version of Flash Player.
For network debugging on a mobile device, you have a reliable network
connection to the device, and port 7935 is open on your machine's firewall.
I have tried
Reinstalling Flash Builder
Starting a new project
Reinstalling Java
Restoring system point
Reinstalling Firefox and flash debugger version for it. verified at this site https://helpx.adobe.com/flash-player.html
All of the steps listed "https://forums.adobe.com/thread/672635" in every post
every related post on stack overflow
Plus some others.
Please if anyone has any more ideas, I'm completely lost as to what to do, If I can't get somewhere on this by this afternoon then I'm probably going to just commit to spending a few days reformatting my drive and reinstalling everything.

Unable to find system thread 1C10

I am developing an Electron app for Windows and within the past couple weeks the app has begun to crash intermittently without any apparent cause. I downloaded the windows debugging tools to examine the crash dumps and found the error Unable to find system thread 1C10. What does this error mean? How can I proceed?

App rejected due to crash on app store

I had developed an app and uploaded it on app store. The app got rejected due to crash. But my problem is that I cannot detect this crash while running app on device for testing. App is working properly on the device.
The app is been created in unity and then I had exported it to xCode.
So I want to ask that how can I get to know about where it is getting crashed. Also how can I traverse the crash log.
Any help will be appreciated
Thanks in advance
Did they tell you about:
– Where crash happened? (At launch, On logging in, or in specific screen)
– Did they send you any images?
– Which devices and iOS they were testing
– They will surely send you crash log, please post it.
You said you cannot replicated the crash, but did you tried with simulator or real devices?
Since you are missing many information, I cannot give you a certain answer. My advice for you is to
1) Updating your question
2) Read my post about how to do when your app got rejected, or my post about how to symbolicate crash log
3) You can also follow the topics in stackoverflow: Iphone App was Rejected Due to We found your app crashed on launch so we were unable to review it and App rejected due to crash. They are very helpful
Actually, app was getting crashed on devices with 64 bit architecture. as older version of unity don't support 64 bit architecture. Unity 4.6.2 onwards support 64 bit architecture. Thus rebuild the ios app and it worked fine.

Delphi Mac OS X

I have problem with Delphi Mac OS X development. I get debug assertion failure error when I try to debug program. My application is just simple form where is few TLabel and TEdit component. Also there is two TImage components where is two images included. And there is also one TProgressBar component on my form. Connection between mac and my pc works ok. It tries to start application when I run it but it disappiers and Windows 7 and Delphi shows error debug assertion failure.
At first there was problem with deployment and my project file was corrupted so I created new project and then I added my old form to new project. After that compiling application works ok but now I get error message debug assertion failure.
I have Delphi XE5 and Windows 7 64-bit.
Mac computer is macbook pro.
PAServer on OSX is a bit buggy and it sometimes crashes with these assertion failures. It's not your application that raises the assertion failure.
If PAServer crashes with an Assertion when trying to start your application, then I'd suggest the following:
1. Close Delphi and PAServer
2. Wait until both have completely shut down
3. Start Delphi and PAserver again
Sometimes this already solves the problem.
If this does not help, try starting your application from OSX from the Terminal and see what happens. Chances are you see an access violation or similar printed to the terminal window. If that is the case you might have a bug in the initialization part of a unit. PAServer likes to crash with an assertion failure if that happens. You'll have to debug the start-up process of your application using F7 and F8. You might be able to speed this up by setting breakpoints in the initialization of some units.
Agree with Sebastian. PAServer is not stable at this stage. There are MANY reports about this:
PAServer can't load dyld: Library
Delphi XE5 PAServer Unauthorized user
How can i debug my DLL project with Delphi's PAServer
Delphi XE4 iOS can't connect to PAServer

Delphi Mac OS X
Solution: wait until they release something stable. (You will have to pay again, of course)
