@sk0m0r0kh I have seen reports in other forums about the 1709 upgrade doing a variety of unpleasant things to application software, as well as creating driver problems. In some cases, shortcuts to certain apps simply have disappeared all over the system; in a few cases, apps have actually disappeared or some of their user account folders have; in some cases, apps have started malfunctioning in some way after the upgrade. Some users have found relief by simply restarting their systems; others have had to uninstall/reinstall the apps; some are still groping for solutions. I'm only guessing, but it may be that Win10 upgrade changes to obscure registry keys or subtle changes to undocumented API's used by certain apps may be involved in these apps issues. At this point, other than trying to reset your Opera profile or trying some of the things just described that have worked for other apps users, I don't know what more to suggest.
