ottohlc ok if this batocera version is working,. use this, is a solution for that ..,
Example
1 - boot batocera .
2 - go to system and choose another HDD reboot. if you use HDD F: change to C . it will create a new recalbox folder on C drive.
3 - on F drive delete all files from recalbox only deserve the roms and bios .
4 - transfer the recalbox folder from C to F .
5 - boot batocera and chooge again drive F and after reboot it will detecte games and run .,
that is config files conflict cause that you are no able to run games . and if games wont boot you are not able to du a reset over retroarch ,.cause that you need create a new recalbox folder to fix this conflict wiht config files .
