Android crash when including ARMv7 in build

Unity 2020.3.33, building and running on an ARMv64 device: All works fine as long as I only check "ARMv64" under "Target Architectures". If I also include ARMv7 architecture, the built APK crashes on startup with:

Code (CSharp):

This just started after I upgraded the project from Unity 2018 to 2020.

Thanks for any suggestions!

 

No stacktrace, just a long list of mem addresses.

I found a workaround in this thread: Delete the Library/IL2CPP* folders, then rebuild.

There's also a bug reported for it, that has been marked Fixed for 2022, but hasn't been (and IMO probably won't be) back-ported to 2020.
