@setiawan for that issue (if it is the same), just disable widgets is the easiest solution for now - https://retropie.org.uk/forum/topic/26322/pi-4-display-issue-with-lr-genesis-plus-gx
regarding the crash, not really sure what it could mean at this point. i guess the issue is around here but it seems pretty generic https://github.com/libretro/RetroArch/blob/c377516db24f999251bec18da414381ff8aab640/gfx/drivers/gl.c#L4174
building retroarch in debug mode might make things easier to debug, but you'd have to mess with the install script for that.
