It s also weird because it says ``Error

[vapid fractal]

Is that the whole log?

It also mentions UnityEditor.BuildPlayerWindow+BuildMethodException: 4 errors

[brisk vine]

I can post the entire editor log, but yes, that are all the errors I get pertaining to the build

[vapid fractal]

During a build all the global project settings are packed together (the ones under <project>/ProjectSettings)

Perhaps one of them is corrupt and causing the build pipeline that creates the global asset unioning them is failing

You could attempt clearing them and adding them back half at a time to narrow down if one of them is failing you

[brisk vine]

I'll try, but I don't see how that can be when I can sometimes build after re-opening the editor

[vapid fractal]

You can sometimes complete a player build, or sometimes enter playmode but player builds always fail?

[brisk vine]

I can sometimes complete a player build

[vapid fractal]

huh

[brisk vine]

everything in the editor works fine

But once it has failed, it will seemingly keep failing until I do some random action, like reopening the editor, deleting library, etc

If I then reopen the editor, and immediately build, it will very rarely work

[vapid fractal]

Would be interesting if you clone the ProjectSettings when it works and compare it to when it fails

[brisk vine]

This never happened on 2021.3.8, so I'm guessing it has to do with the update

[brisk vine]

I'll try copying them when it works, and diff against when it fails

Is that what globalgamemanagers.asset is? Just all of those assets combined?

[vapid fractal]

Quite possibly. This problem would be inside Unity itself (If something on your end isn't trying to manipulating/add settings etc...)

That is my understanding from some digging.

[brisk vine]

I'm not doing anything fancy with build settings

[vapid fractal]

I can also see someone in the past has had a similar issue but it was caused by a third-party lib attempting and failing to write out a configuration asset

The sometimes nature of your problem is very suspicious. So if nothing stands out from comparing when it works vs fails, the best thing to do would be to Report a Bug and include your project (or subset) so the build pipeline team can take a look as they would be very interested

[brisk vine]

I'll try messing around with the ProjectSettings and seeing if resetting them helps, I'll send a message in this thread if I figure anything out. Thanks for the help

[vapid fractal]

Sounds good.

No problemo, sorry I don't have anything more tangible atm

[brisk vine]

No worries, things like these can be nightmarish to figure out...

[brisk vine]

After deleting the entire ProjectSettings folder and manually setting the few settings I use, it seems to now build correctly. I have no idea what the issue was. Version control does show me a lot of changes on the files that were in the ProjectSettings directory before though.
Thanks for helping me with this, it was supremely frustrating!

[vapid fractal]

Awesome!

If you still have the bad files, I'd recommend still logging a bug so the pipeline team at a minimum can improve the error reporting for this

[brisk vine]

Sure thing. This is just a hunch, but maybe this was also related to the pre-splash crash bug that I sometimes had, since I now have a seemingly new version of the splash screen
