I have been using 3.1.1 on Windows 11 for months, usually daily. Even earlier today without an issue. But an hour ago it opens minimised, and won't open a normal window.
The taskbar preview shows just a white block that I assume might be an error message, but I can't read it. This occurs with opening a CBR, images or even just the app itself.
I have rebooted my PC, uninstalled and installed again. Installed 3.1.0. None of this has fixed it. There have been no system changes today, so I have no idea what happened.
I finally tried deleting the \AppData\Roaming\MComix directory and that seems to have fixed it.
Must have encountered a corrupt file or similar.
