    Posting a follow-up in case anyone else runs into this issue: for my project, the issue was caused by having ARM64 enabled when using the IL2CPP scripting backend.

    I went Edit -> Project Settings -> Player -> Android -> Other Settings -> scrolled down to "Scripting Backend" -> unchecked ARM64. After rebuilding, I had no more issues.

    This is not fixed. It has been happening since Unity 2022.1.24f1, and every stable version since then (incl. 2022.2 versions) has had this issue.
