I have been having SEVERE performance issues with Premiere for the longest time. I have pin pointed it to an issue with the TITLE PANEL being open while trying to work on the project.
I never had this issue about 4 updates ago and it seems to be the same with my TEAMS programs as well. Program works fine if the panel is closed, but is USELESS when the panel is open.
Sorry for the issue with titles panel. Is there an error message after the crash? Share a screenshot with us.
Also, please elaborate the exact workflow to recreate the issue.
