Can't see my plugins anymore (Home Assistant 0.108.9 Rpi and Docker)

Hello,
I can’t see find the plugin menu in HA frontend anymore. I also get the “Unable to load the panel source: /api/hassio/app/entrypoint.js.” when I try to open configurator.
I am running on docker.
Can anyone please help?
I need to update my plugins and are stuck!
Thanks for any support!
