Editor crashes while launching to Oculus Quest

This crash happens every 10 minutes and I have no ideas why this is happening.

The crash reporter shows something like this:

Assertion failed: !Export.ClassIndex.IsNull() [File:D:\Build++UE4\Sync\Engine\Source\Runtime\CoreUObject\Private\UObject\SavePackage.cpp] [Line: 5091]

I don’t even have a D drive. Can anyone help me or something?

I am getting this too when launching to Quest. I’ve just installed 4.23.1: I wonder if that is the issue?
