I'm trying to export within Premier Pro using match source either high bitrate or medium bitrate, and anything related to match source automatically stalls the program and shows zero percent progress. The exact same thing happens when trying to export using Media Encoder. I'm able to export using match source on all other projects. I've made a new file and copied over elements from the file that doesn't export and the same issue occurs.
What are the next steps that I should be taking to troubleshoot this issue?
