From the log it looks like the game crashed in the middle of printing a log message, which I don’t see very often at all.
As far as I know, there’s one physics related crash / random lockup that happens occasionally:
We very much would like any help regarding fixing this issue. Notice how it’s been open since May last year…
One good bit of news is that Godot 4.0 changes to a different physics engine, which may resolve our issues with that as well.
As to the computer lockup stuff, I think it is caused by the game infinitely spamming the same error message when it freezes. I’ve reported this to Godot to try to get in a fix that would limit that: Error printing to logs from Godot is not rate limited · Issue #45181 · godotengine/godot · GitHub
Besides that, our launcher probably makes things worse as it keeps the log messages in memory, so I’ve also already opened an issue there to limit that:
It might take a while for that to be fixed as the launcher gets even fewer code contributors than the main Thrive repository.
