No regions or widgets error

HI.

Unfortunately all my windows players face the same problem No regions or widgets 5000 error. The xibo player splash screen appears and after a while, the client restars the xibo player. THis is a constant loop. I tried reinstalling the client, i recreated my campaigns, nothing works and i don t know why. Any insight would be appreaciated. I use the latest player , and cms in a docker environment.
