Try this way out, for me worked on lir-v302 .
I have set Rendering mode = Backend - OpenGL in the application on stock FW (by default Vulkan is set there, therefore the application does not start, IMO) and extracted from phone. Download
link .
Install linked app, then go (restart your phone if needed) to Settings/Apps/See all/ open "PPSSPP" > set permissions (all) and use "Force stop".
Go back to the main screen and launch PPSSPP. It should work, in app logo you will see 'Open GL ES' in the bottom line. GL!
