Hi! I'm using v. 20.5.1 of Animate 2020 and I need to export a quicktime or H264 (to AME) of my animation. Everything goes fine when exporting from the original project file where the work has been done, but if I try to make the same thing from a copy it starts exporting, then immediately stops and Encoder's rendering queue appears to be completely empty. I also tried to export a .mov directly on desktop without using AME, but it won't open and it's only 4 KB, as if it was an empty quicktime.
This happens also if I simply move the .fla file to another folder and reopen it. This problem is solvable by choosing other formats like PNG sequence or SWF, but I would like to know if anyone else encountered this issue.
