Blocking call stops Lovelace and makes HA crash

[thedmmatt]

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:

1. Go to 'Integrations'
2. Select the UI Lovelace Minimalist integration
3. Click on 'Configure'
4. Make any changes and try to apply them
5. 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

Additional context
Running HA as a Docker container over WSL2.

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

I fixed two issues with my limited knowledge of Python and Home Assistant. You can find the modified files init.py and base.py in my GitHub repository https://github.com/wilbiev/UI/tree/main/custom_components/ui_lovelace_minimalist
The solved issues are the hanging (problem in the reload of the integration) and the log messages 'Detected blocking call'

[wilbiev]

Fixed hanging issues for (first-time) users not using the GitHub option. Update in https://github.com/wilbiev/UI/blob/main/custom_components/ui_lovelace_minimalist/__init__.py.
PR created.
Other issues were fixed in new available version v1.3.10
