which was running fine before update of Recalbox

You probably have some configuration conflict from an earlier version, I recommend that you update your gamelists (to be more agile, use external software such as Skraper or ARRM ).

In addition, in these cases it is recommended do a factory reset (option available through advanced settings since version 7.2), you will not lose any personal data, but the system will delete all customized configuration files, if there is any configuration conflicting, it will be eliminated.
