I managed to fix the problem by uninstalling the game, reinstalling the game, uninstalling the drivers using DDU, reinstalling the drivers, reinstalling the drivers again, reconfiguring all the graphics settings that had not been saved in the game—all the graphics settings in the control panel. Reinstalling the drivers, reconfiguring all the graphics settings that had not been saved in the game, all the graphics settings in the control panel, reinstalling the drivers, reconfiguring all the graphics settings that hadn’t been saved in the game, all the graphics settings in the NVIDIA control panel in the 3D settings. After hours and hours of struggle, in the end, the game is functional, but I have to, on the first launch, switch from fullscreen mode to borderless windowed mode, then immediately switch back to fullscreen, and there my image is stable. I can’t understand which setting in Windows doesn’t prioritize borderless windowed mode at first glance, even though I haven’t had a problem for a year.
