Roborock Q10 X5: Setting up integration not possible

Received a new Roborock Q10 X5 last week.
Read that support for the Q10 will be added with the 2026.4 release.
Unfortunately i´m absolutely not able to complete the setup of the integration.
I always get an “unknown error” after the input of the mail adress.
Log file contains always the same error:

Tried to revoke the authentication as described here:

No success.
Any ideas?

you have a custom integration that is pinning pyrate-limiter to a lower version. You’ll have to look through your custom integrations and figure out what is causing it!

Strange.
I have absolutely no Roborock extension running.
There is noting left in my configuration.yaml.
Only thing is the Xiaomi integration for my pedestal fan.
Tried deactivating it, no success.
