Building with IL2CPP gives 'Fatal error in Unity CIL Linker'

Every time I try and build using IL2CPP I get the error below. Building with Mono is fine, but it’s a DOTS project. I have tried DOTS 1.2.pre-4, 1.2.exp-3, 1.0.16, and a few editor version to see if it made a difference (2022.3.15-13-and 10) but had the same result in all tests.

// This keeps going on after --allowed-assembly for dozens of assembly paths

I tried adjusting the managed stripping level from minimal to low, just to see as well, but no change. I also tried setting C++ Compiler Config, and adjusting the IL2CPP code gen setting, but so far, none of them seem to make any difference.

I am really not sure what else to try?

Current setup outside of testing the other versions:
Ubuntu 22.04
Unity 2022.3.15
DOTS 1.2.pre-4


Edit. At least some good news, I tried a different project with the same Unity packages installed and it built, so I guess it is just something in my current project. That makes me feel somewhat better. Just gotta keep digging.

I tried to match up the working project with my current project, and somehow… it was the scene that caused this? I created an empty scene and did a build and it worked. Doing it with my test scene, it gives the linker error. I am not sure what is up with that, but at least it’s progress.
