Same issue here.
Alpha 2 crashes, but opening the very same project with Alpha 1 works.
Crash occurs on building the project.

3.2 Alpha 2 (mono version) here:
I am not sure is related but at least part of the error messages I'm getting are the same.
It happens even without launching the game, just leaving the editor opened for a while, now I have the editor window disappeared, and only the console visible.

Super weird, I have 0 mono scripts now, just GDScript. So, I hope this really closes the issue, anyhow I'm moving back to the classic version, I am not using C# anyhow LOL...
