Hey, I’m unsure if this is related at all but I’m having a kind of similar problem, except that I can’t do anything at all on studio, it won’t let me move (drag) parts using the select tool, won’t let me switch to move/rotate/resize and so on. One thing that I noticed is that it also wouldn’t allow me to open my Toolbox.
It has been happening since two days ago afaik, and it happens kind of once everytime I edit a new game or after me not opening Studio for a while. It fixes itself when I closed and reopened Studio. Nonetheless, it gets kind of annoying due to the fact of me having to keep restarting Studio.
