Just downloaded 12.1. 120. worked fine, but in 121 I send a timeline to Media Encoder from Premiere, and it loads in the queue. I then press start to encode the file and nothing happens. Encoder just sits and doesn't encode the file. Then I press the stop button, then I try to close AME and I have to force quit it to close the program.
I have trashed the preferences and restarted my machine multiple times, all to have the same issue.
