Integration not working in HA after update

[Peet3kabo]

Yesterday I did an update to the latest version of this add on.
After that I have no working integration anymore.
Tried restart of HA, restart the wallbox.
I can reach it thru the myeve app, no idea what else to do.
Have an error in the log of HA:
Deze fout is ontstaan door een aangepaste integratie.

Edit, if I try to reload the integration it gives the message to restart HA to finish the installation. Looks like it's stuck in a installation somewhere. Did restart HA several times but that didn't resolve the problem.

Edit 2, I did several updates on hacs in one go before restarting HA. Also it was before I updated to the latest HA version. So restored backup to a previous working HA, the day before........then updated HA to latest version, next step was update alfen integration and restart HA. Same problem occurred with same error message
