Webpage did not start on Home Assistant, but Raspberrymatic still working

[Fiiti]

Describe the issue you are experiencing

Clicking on "RaspberryMatic" in Home Assistant did not start the Webpage.
I get shown "The add-on does not seem to be ready yet, maybe it is still starting. Do you want to try again?".

But the Add-On ist startet and green.
Of course I restartet the add-on and the whole system many times.

Toda I updatet to the latest version: 3.75.7.20240420 - but I cannot say if this is the purpose of this issue.

Describe the behavior you expected

CCU Startpage should be shown.

Steps to reproduce the issue

Click on the PaspberryMatic Button direct in the left panel.

3.75.7.20240420

Which base platform are you running?

Additional information

I did not know, how I can go back to the latest Version before.
Is it for tests possible?

I am also tried The HACS HMIP Integration to set to version 1.58.0 and tried also the Version 1.60b .

So what can I do?
