I recently updated to Processing 3.3.5 and now I can only run the Movie Maker tool once per session - i.e. if I launch processing and run the Movie Maker tool, I have to restart Processing before I use it again. I don't get any error messages, but the 'create movie...' button is greyed out, even though there is a path specified to the frames folder. I've checked a bunch of times and the path to the frames folder is correct. If i restart processing and use the exact same path, it'll work - but just once and then I have to repeat the whole process again...
