Unable to install myVAILLANT integration

Problem description

After updating Home Assistant -
Core 2025.3.4
Supervisor 2025.03.4
Operating System 15.1
User Interface 20250306.0
I lost access to the integration...
In accordance with previous experiences, I decided to remove the integration and install it again. The download process itself went smoothly, but now I can't add the integration itself - when trying to add the integration I get an error - 500 Internal Server Error Server got itself in trouble
