Same here 
Windows 11 Home on Samsung Book 360 Pro.
At this point every single time the laptop wakes from sleep Opera is frozen solid and the Task Manager is the only way to close the browser!
Really frustrating to say the least.
Tried to reach out to support to no avail. No response and I don't expect one any time soon as you need to include a screen shot of the issue. I attached a random picture.
I have used Opera for years now both on a laptop and Android but now heading back to Firefox as my default as sync issues have been resolved.
Bye bye Opera...
