@burnout426 please tell me how I should switch to opera://bookmarks if I can't open the browser?
synchronization in the background was enabled in the account, but I don't think this plays a role
in the main opera, I found that authorization synchronization was reset after logging in, tabs in several spaces were connected to the first space, I had to manually separate them
none of the problems described by the link even indirectly relates to the problem, but just in case I tried all the recommendations suggested there: reinstall C++ run the old installer
the only thing that reacts to the launch is opera_autoupdate.exe which creates an empty opera_autoupdate.log
it says here that you need to save a backup copy https://help.opera.com/en/latest/crashes-and-issues/#backup but I have not found where these files are located
I don't know if it matters, but the Cumulative update for Windows 11 for systems based on x64 processors, 2022 09 (KB5017328) is not installed for the 3rd time, although the rest of the operas are working fine
please help
