I'm trying to use the knife tool. I click on the tool and it does appear.
But when I try to press LMB to cut, instead of the guidelines I am supposed to create appearing, the only thing that happens is that only the green square that marks the beginning appears, and it always appears at the source point of the object. (you can see in the gif I added that i'm trying to click and nothing happens)
In addition, from time to time it happens that the tool does respond to my clicks. (It should be noted that sometimes it reacts and sometimes not. In both cases it happens for no apparent reason) But even when the tool responds, it seems that for some reason it constantly insists on choosing the edges of the objects instead of creating edges the way I draw with the mouse.
I tried of course to check if it had anything to do with the edge selection mode, but no matter what mode I was in or what object I tried to perform the action on, All I could do was make this green square appear and nothing more.
I believe this is some definition that has changed in this specific project, because in every other project the knife works properly.
