So in a total “WTF?!” moment. The problem worked itself out. I spent a whole afternoon trying to get it to work with multiple uninstalls and computer reboots, but nothing worked.
However I installed the newly released engine build and then the previous one (that I couldn’t get to work) and the problem seems to be gone. I don’t have a clue why.
Maybe installing the new engine version fixed whatever was causing the problem. I don’t know. Thank you for the help anyways.
