I've reinstalled Garuda linux today, and I have it 2 weeks ago. Persona 4 Golden was working but today it didn't. It seems related to certain updated version, maybe Proton. Persona 4 Golden is working in my Linux Mint machine.
Welcome. Please try to run the software from the command line and note any error output. Could be a dependency issue. For things like that, reverting to an earlier snapshot and waiting before updating again is usually your best bet:
