since a week or so I am experiencing the odd situation that Opera seems to be frozen immediately after starting it. The loading icon in open tabs seems frozen, if I click into the input line no cursor appears and I can't type, I cannot open new tabs or close old ones. After 30 seconds or maybe a minute everything works fine again.

So far I tried to close all tabs, empty and delete my whole history but none of it worked. I did not install anything particularly new or changed things in my OS or in general, it was simply just there. My Opera version is

Version: 111.0.5168.55
Windows 11 64-bit
Chromium-Version:125.0.6422.143

In some older threads I've read about a similar problem where people suggested to deactivate synchronization. However, my synchronization was never activated.

Any help would really be appreciated. Thank you!
