Premier Beta-can no longer export!!!

[leeh16807075]

Updated to Monterey on a 2019 Macbook Pro, as the latest version of Beta no longer works with High Sierra. The latest version of Beta will not let me export to Encoder and tried multiple projects and files. Get an error message stating access is denied and that the files are locked but they are not. Error message frame cap attached. Same with previous versions of beta Please help!!!!!
