Why is IL2CPP hanging or taking so long to finish? 8 hours in.

Hi all, So I've been working on t$$anonymous$$s XR Android mobile app with IL2CPP as the targetted backend. I've been able to build the .apk out to a folder or device fine for the past few days with it on average taking 2.5 minutes, but sometimes IL2CPP will just hang for a good 5 - 10 minutes and need me to restart my PC since I can't kill the il2cpp.exe process.

I left my PC to build the .apk overnight, and it still hasn't finished. It's been 8.5 hours...

Only t$$anonymous$$ng I've noticed to fix t$$anonymous$$s is to just keep restarting the PC till the build works. Iterating t$$anonymous$$s way is definitely not ideal when I just need to check spacing/ any other small change.

We need to use Unity2020.3.30f1 for compatibility reasons.
