Premiere Pro wont launch - loading importerquicktime.prm
This problem didn't exist for me not even a week ago, but suddenly did when I tried to launch Premiere Pro yesterday. When I try to launch Premiere Pro (14.9), the launcher freezes indefinitely on the step "Loading importerquicktime.prm". I can't even end the task through Task Manager when it starts Not Responding, I have to restart or shut down my laptop (Windows 10.0.19042).
I've tried a number of things to resolve this issue, including uninstalling and reinstalling Premiere Pro, Creative Cloud itself, resetting OneDrive (where my AppData file is), changing folder access settings in Windows Security, and other remedies people have listed on forums, but to no avail. I don't want to have to reinstall Windows if I don't have to, but I can't think of other options. The only Windows updates on my device since being able to launch the app last (2/15/21) have been Windows Defender Antivirus and an update to remove Adobe Flash Player (2/19/21).
Anyone have any sure fire ways to fix this? Incredibly frustrating, thanks in advance.
