Okay, sounds like you've turned on Vulkan. Vulkan isn't working on Android right now - you can turn it off on any of the builds where it's mirrored (might be hard), or you can just delete PSP/SYSTEM/ppsspp.ini from your phone's storage to reset your settings to defaults.

It's not an option now to turn on Vulkan on Android, until we figure out why it's not working.
