Hello, i am pretty new to unity, i'm a stuudent. I've been working with pro builder which is great. However, last night unity crashed while i was editing UVs with probuilder. Now everytime i open unity, an empty floating window is covering a small part of the editor. Luckily its not preventing me from being able to work, but it is still pretty big and quite annoying. I can't close it, can´t drag it, can´t interact with it at all. Opening the UV editor again just opens a new window instead. I really don't know how this happened.
