Unity 2017 crashing when during Debug Step Over - visual-studio

Using Unity 2017.4.
When I run a debug build the process stops at the breakpoint correctly. However, regardless of the breakpoint location, as soon as I press 'Step Over' just once, Unity crashes. This happens when using Visual Studio or MonoDevelop on my MacBook.
Here is the crash report. Anyone know how to fix this?

Find this path with terminal :
/Applications/Visual Studio.app/Contents/Resources/lib/monodevelop/AddIns/MonoDevelop.Unity
-Then you will find a subfolder "MonoDevelop.Unity"
-You need move all the files and subfolders in MonoDevelop.Unity/MonoDevelop.Unity to the first MonoDevelop.Unity directory.
After all these steps,
-You can delete 2nd MonoDevelop.Unity folder.
Hope this will help.

Why does launching iOS Xcode simulator create Crash Report after MacOS Catalina upgrade, and what to do about it?

Recently upgraded my Macbook to Catalina OS v10.15.1 and have since been experiencing performance problems with the Simulator in Xcode (11.2.1).
To be precise, the simulator is working OK, but my Macbook fan starts running high immediately after launching the simulator, then the laptop starts to get very warm. This follows up with a Crash Report from process searchd (below). The process Launchd_sim is also taking lots of CPU processing according to Activity Monitor (also below).
Strangely, the simulator works fine but the Macbook fan is running abnormally high and is very hot. I did not have this problem prior to going to Catalina OS.
When quitting the simulator, the fan slows to normal speed and the machine seems to cool down. This situation is repeatable. Anyone else seen this problem?
Simulator version is 11.2.1 (SimulatorApp-912.4 SimulatorKit-570.3 CoreSimulator-681.15).

macos crashlytics crashing while sending report

i have an issue with my (first) macOS app. A beta Tester gets a crash right on start of the app.
I am a bit puzzled as to why.
I have included the crashlytics framework (Version 3.9.3 (128)). It seems to me that is crashing while crashlytics is trying to send a report (from an earlier crash?).
has anyone experienced something similar?

Mike from Fabric here. I don't believe that this is a crash within Crashlytics. You'll see our threads referenced in most crash reports because our processes are waking up to catch the exception.
The error you're seeing is usually due to memory mismanagement or holding onto an object that's no longer present.

LLDB Makes Xcode 5.1 Crash on Project Run

I've only started using Xcode from this morning, although I have it for a while now. Anyway, for working mostly on C projects I used Netbeans...
To make a long story short, I noticed this morning, right after creating my first project, an OS X C Command Line Application, that when running (CMD + R) my project, Xcode crashes right after building it. It crashes exactly when it's running the project.
It doesn't give any error message, the program just quits. As I am new to Xcode, I have no idea where to find an error log file, I don't even know if there is one. Although if there is one, I would like very much to know where to find it. Searching on google didn't help me at all to locate this file.
First I thought this issue was addressed only to OS X C Command Line Application project. As a result, I tested with several other project types and I've got the same output.
Anyway, I've managed to work around this problem by selecting no debugger for my project in Product -> Scheme -> Edit Scheme -> Run -> Info tab:
However, my projects run now, I still need a debugger, therefore this is not a fix for me.
I have also tried uninstalling and installing back Xcode, but the problem didn't disappear.
Is this a common problem or is it only me? I've seen other people complaining about problems related to mine in previous versions of Xcode, but most have found a valid solution for them that I tried as well but with no luck.
Does anyone know how to fix this issue? I am pretty desperate and the only 'solution' left in my mind is to see if reinstalling the OS will help me, which I would rather not do.
I forgot to mention, I am running the latest version of OS X (10.9.2) on a MacBook Pro Retina 2013 machine. Also, I've got the latest version of Xcode, 5.1 (5B130a).
EDIT
After creating a new user and doing the steps above I managed to get an error message from Xcode:

I had the same issue and fixed it. See https://stackoverflow.com/a/14414016/968427.
Check the /etc/hosts file and ensure the host(127.0.0.1 localhost) is exists.
Apparently, this wasn't a common issue, it was only affecting me.
They only way I managed to make Xcode work as supposed was to delete the app and reinstall the whole OS.
UPDATE
The bug appeared again shortly after I installed Xcode again. Therefore, I opted for a full reinstall of the OS (format the hard drive as well).
Nevertheless, after a few weeks the bug appeared again. Anyway, this time I noticed why this is occurring. The reason for that is something related with MAMP PRO MySQL port. Only if I have MAMP PRO MySQL server running, Xcode works.

D3.js rendered page crashes on all major browsers on Mac but doesn't crash on Windows or Ubuntu

I have an eleborate web page built with d3.js, with lots of elements, animation and event-listeners. And it crashes on Mac (both Safari and Chrome) when I start actively using it. Works fine under Windows and Ubuntu though.
Here's head of crash report (Safari) (I can provide full stack if needed):

Webview crash with Garbage Collector ON

I have a very specific web page that causes webview to crash with the Garnage Collector ON (does not crash when OFF).
Easy to reproduce: create a document base application, drop a webview, and have the following line (button perhaps).
- (void)connectSearch:(id)sender
{
[[webView mainFrame] loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:#"http://apple.com"]]];
}
I guess this scenario is only valid while Apple advertises their new iPad. At the bottom of the page there is two video you can watch. Click on the one on the right. When it is playing, click on the Close button (link) top left - which sends #SwapViewPreviousSelection - and that's it, it crashes.
I'm just learning about the garbage collector but I suspect something is collected that should not.
Any idea what can prevent the crash, other than turning off the garbage collector?
Thank you.
Here is what I get:
