I’ve run into this problem several times now. It’s possible that there’s something wrong with my mouse (Razer Synapse issue) so I’m going to check that now. However I’ve spent the last few days I’ve noticed several commands in my context menu are greyed out. I primarily use hotkeys for some of them but things like “Intersect Faces” is greyed out. I’m attaching a screenshot of what I mean.
Anyone have any advice?
