Faulting module name: mono-2.0-bdwgc.dll

How do you find the cause of a unity to crash if you only get something like this (same result for Unity 2019.4.XX + 2020.1.XX):

that's all i get. The application itself is starting, I even get log entries but something within the project seems to make it crash before the scene got completely loaded. Any ideas how to get more information out of it?

 

I had the Fullscreen mode at Project Settings -> Player -> Resolution and Presentation set to Maximized window. That kind of suppressed the error messages, I set it to windowed and finally got at least an error message I can work with.
Nevertheless this looks like an issue with Unity, you should always get at least an error message regardless if maximized or not

In my case it seems like XML Layout is causing it:
Crash!!!
......
Trying to add Label (UnityEngine.UI.Text) for graphic rebuild while we are already inside a graphic rebuild loop. This is not supported.
.....
0x000001BD1A5EC11B (Mono JIT Code) UI.Xml.UIExtensions:SetOptions (UnityEngine.UI.Dropdown,System.Collections.Generic.IEnumerable`1<string>)
....

 

I have started getting this error but when i try to do a build. Unity will sometimes crash with this error.
Have you found a fix?
