#Fatal error. Failed to load JIT compiler.

A colleague is now consistently getting this error when launching unity, forcing him to start in safe mode.
It started to happen out of the blue with no significant change made to the project, and it worked fine for him before. And it seems to work fine for others, so it's probably at least partly tied to his machine. But I have absolutely no clue what to do about it.

Any advice? This is super weird

Likely a corrupt unity installation. Kinda hard to say anything more than that without more context/info.

The exact log message(+maybe other messages around it).
If it's a crash, then crash report (at least the callstack and the last logs) from the editor logs.

#

Maybe screenshots too if there's anything to share beside log messages.

I asked him for the logs, though he may be sleeping rn, give it a couple hours

#

It's not a crash anyway, just the editor not working
And no further info on the error in the console

Did they try reinstalling the editor?

But yeah, it's quite likely a corrupt unity installation or project cache. Try:

  1. Deleting the library folder and letting unity regenerate it.
  2. If that didn't help, reinstall the editor.

Ah
It says - langversion: 9.0

The whole thing is probably starting some 10~30 lines above.
