    Can you tell us what version of Burst you are using? And was this an editor issue or were you building for a specific target?

    It looks like you've got non ASCII characters in your Windows username, and I've dug into our code a bit - and while we do support proper UTF nearly everywhere, it looks like in the case where we need to generate LLVM intermediate files (the .bc you see above) we are relying on C++ side code to store that to disk, and we are not correctly translating from the correct path-with-UTF to C++'s equivalent.

    I'm filing a bug internally for this, will keep you posted.

    Unity unfortunately has a long history of regressions that keep popping back up when using paths with non-ascii or space characters. Unity's QA team should add more regression testing coverage in this area, but if you want to save yourself some unnecessary headache just keep everything in ascii compatible patths without any spaces. I think I hit one of these back in the Unity 4.x days, learned my lesson, and it hasn't hit me again since ;)
