Blocking call stops Lovelace and makes HA crash

Describe the bug When trying to change anything in the Integration config page (for example, a simples edition such as disabling adaptative dashboard), HA starts logging the same message over and over again until it becomes unresponsible and/or crashes, requiring the container to be restarted.

To Reproduce Steps to reproduce the behavior:

Go to 'Integrations'
Select the UI Lovelace Minimalist integration
Click on 'Configure'
Make any changes and try to apply them
See the error in the logs

Expected behavior Any changes would be saved by the integration or errors would be printed in the popup header without crashing HA.

Screenshots n/a

Additional context Running HA as a Docker container over WSL2.

Yes -- weirdly enough, the error log stops right there with an open parenthesis
