Adobe Digital Editions not opening

I just experienced problems with the ADE. I have been using it for months now, sometimes without any problems, sometimes it bugging more than I'd like to. Few days ago it stopped working, I've uninstalled it and installed it multiple times without any help. Tried to chat with the support, but they said they are not offering any support with Digital Editions, and I need to find the answer myself. When I try to open it, I can see the logo on the taskbar and when I click on it, nothing happens. Sometimes when I click it, there appears/flashes about 5x5cm white square on the left side of the screen. Nothing seems to be working. I currently have Windows 11. Any help?
