Resolved Unity Player crashed now no player opens properly anymore

Resize is greyed out.

ALT+Enter does rescale the window to "full screen" but the canvas seems to remain a few pixel height and unresizeable


My unity player crashed, now all unity players open minimized and I am unable to open it again and by all I mean every single build I ever made. Reboot did not help. Deleted all registry keys I could find to this particular path, but as it affects any unity player I ever made it must be something windows window manager related or unity player related...

OS:Windows 10

I have never seen this and am glad for any ideas or help.

Edit: Okay, it definetly is tied to the windows user. I have created a new user and there the application opened in full screen, when window mode was expected - but it did work. I really wish I don't have to create a new one, but can fix it.

Edit: Was able to fix it:
- Create a link
- Force Maximized
- Start

Now all other applications work again as well . IT can be so so stupid.
