Citra on macOS crashes on subsequent rom loads

citra will load a rom once but any time I try to load that same game a subsequent time the whole application crashes. I have to fully uninstall the app to get the same game to load twice.

I did not find anything wrong in your log file. Please wait for a moderator to assist.

Disable the Disk Shader Cache in Citra>Preferences>Graphics>Advanced Tab.

wow. yes that seems to have done the trick. is there a faq somewhere that I missed where I should have caught that setting?

No, this issue is something that occurs on some MacOS versions. Has to do with Apple routinely axing support for this and that and us not wanting to bother adjusting our code or information to their whims. For example, High Sierra used to run Citra just fine, until they cut support for something vital, now it doesn’t run at all (users are forced to use an older Citra version). Big Sur introduced specific issues with Hardware Shaders, so on so forth.
TLDR, not your fault, blame Apple.
