(Admins feel free to delete this if its not okay.)
I have 7.1.1 backed up on Google Drive for all platforms. I rolled all my devices back to this version as I find 7.2 unusable in my use case.

I'll stay on 7.1.1 until it's fixed. Love my achievement hunting.

This bug only seems to occur when you use RetroAchievements and a CHD compressed game at the same time.

I have the same issue, I tried the system driver, and it partially works, but there are all kinds of errors. Buttons won't map right in game but are right in menu, hot key doesn't work (randomly changes through shaders), and can't exit emulator. This is with SN30 pro+, on system driver, with B+Start (Android pairing mode).

I tried loading the .chd compressed games on 7.2 and they crash with the error message:
8<--- cut here ---
Unhandled fault: alignment exception (0xa21) at 0xaf75013c
pgd = 0e8ade62
[af75013c] *pgd=02f32003, *pmd=1ef0e1003

This happened when I tried PCSX-ReARMed and Duckstation for PS1, and it happened for Dreamcast chds as well. This also occurs on both an upgrade from 7.1.1 on a Pi 4 and on a fresh install to a new memory card on a Pi 4. These games worked in 7.1.1.

Also want to confirm a previous post about 8bitdo controllers not working in game on 7.2. Have an SN30 pro and a SN30 pro+, neither work in game.
