Calibre ebook viewer not opening

Not just while opening books, even if I simply launch the ebook viewer directly from start menu, the same thing happens.

I tried running Calibre in debug mode but it seems to have entries about Calibre management app only, not the viewer. I updated to 4.20 as well just now but same issue. Any idea how to fix this?

In Calibre 5.43 when I use the view button, the icon appears on my Windows 11 toolbar but no window opens. When I hover over the icon that appeared on my toolbar it shows an empty mini-window above it with the name of the ebook I was attempting to open. When I click on this empty mini-window it dissapears but nothing appears in the screen. When I go to that very same ebook file with file explorer and right-click it and choose open with the calibre viewer it opens normally.

Any ideas to fix this problem?
