Launch error | There is a problem launching using posix_spawn (error code: 2) - xcode

I am currently working on a project through github. My local project is connected to the github project folder through folder reference.Current File/Folder setup There hasn't been a problem, but now I keep getting the error "There is a problem launching using posix_spawn (error code: 2)." Before that, earlier today, I was receiving the error: "could not launch 'PROJECT NAME'. Internal error"
with the initial error ("could not launch 'PROJECT NAME'. Internal error") I attempted to fix the Schema configuration by following option B in this link (https://github.com/olilarkin/wdl-ol/issues/120). After attempting that I began receiving the later error ("There is a problem launching using posix_spawn (error code: 2).")posix_spawn Error
please help. Thanks

PhoneGap Build: Error: NOT_FOUND_ERR (missing files)

When I try to use my app from PhoneGap Build, it seems to be missing images. When I check in the Chrome web inspector, it's also missing script files. Here are the errors:
cordova.js:314 Uncaught Error: NOT_FOUND_ERR
at fileService.js:77
at fail (FileEntry.js:88)
at Object.callbackFromNative (cordova.js:295)

.png:1 Failed to load resource: net::ERR_FILE_NOT_FOUND
I know I didn't fail to include this file, because it was working before.
Most issues like this, as well as "Upload Error [2]", can be solved in PhoneGap Build by deleting the app and re-uploading. Don't worry about losing anything, since all of your settings are in your config files. It seems that PhoneGap has a tendency to inadvertently retain or misplace files.
I tend to just delete my app and re-upload every time I need to run a build, so I don't have to waste time installing and opening the app, only to find out it's missing files.

Error at launch app

When I launch app sometimes I get this error and sometimes no:
2017-11-10 14:00:37.119701+0000 XXX[768:176399] [DYGLInitPlatform] connection to host has failed: Error Domain=NSPOSIXErrorDomain Code=2 "No such file or directory"
2017-11-10 14:00:37.123363+0000 XXX[768:176399] aborting: platform initialization failed
(lldb)
What can cause this problem ?
There could be some corrupt files in your build folder.
Try running Clean (⌘+⇧+K) and Clean build folder... ( ⌘+⇧+⌥+K ) and rebuild your application.
In my case, the error was related to Launch Screen, most likely it was corrupt.
Deleting the launch screen under General Tab, fixed the issue.

Deployment error: windows.licensing failed to start WSService

I get the following error when I try to deploy a windows store app:
Error : DEP0700 : Registration of the app failed. error 0xC0020017:
windows.licensing failed to start WSService while installing
My developer license is valid. I changed the package name, still the error persists.
This problem occurs with old and completely new projects.
Does anyone have an idea how to solve this?
Registration of app failed error usually occurs when you try to re-deploy an app with the same package ID from visual studio if it is already installed by a different user.
Solution is to change the Package Identity
Open the manifest
Go to the package tab
Modify the identity
