I've update to 7.2.2
There is a possibility that you are taking advantage of configuration files from the old version, and this is conflicting with something, I recommend that you try the factory reset, available through the advanced settings menu. This will not affect your personal files, but it will erase all custom settings.
I have OPL
Since the OPL is not officially supported by Recalbox, there is a possibility that it will no longer work, but that doesn't mean it's a Recalbox bug: the system wasn't made for it.
