upgrade crashed recalbox

Hi,
recalbox proposed to upgrade from 8.0.2 to 9.2.3 pulsar.
After reboot frontend.log shows:
[2024/12/30 17:19:29.660] (ERROR) : [MainRunner] Error while parsing systems configuration file!
[2024/12/30 17:19:29.668] (ERROR) : [MainRunner] IT LOOKS LIKE YOUR SYSTEMS CONFIGURATION FILE HAS NOT BEEN SET UP OR IS INVALID. YOU'LL NEED TO DO THIS BY HAND, UNFORTUNATELY.
