This seems to be an ongoing issue across versions, operating systems, and years. I don't know who to convince at Adobe that there is a legitimate bug causing this and for them to roll out some sort of fix.
I'm using a Mac running OS Catalina, and Premiere Pro CC 2021 version 15.2. For whatever reason, Premiere Pro started hanging on startup every single time on "Loading ImporterQuickTime.bundle". I have uninstalled/reinstalled; employed the variety of solutions such as repairing permissions on my Mac; deleted the DynamicLink thing; deleted my user preference folder; and deleted the QuickTime plugins themselves in the past - all of which resulted in sometimes fixing Premiere Pro only once - and then the next time, it goes back to hanging at the same spot. What is the actual reason this is happening, and what is a permanent fix for it?
Any other plug-ins or extensions you can remove?
Not that I know of. I've never used any outside plugins or extensions with Premiere.
Are there any other suggestions you have?
Sorry for the trouble. Have you already tried moving your default plugins to desktop and then test it? Navigate to the default plugin location and move all the plugins from the MediaCore folder to a folder on the desktop and then check if the app is launching properly.
Default plugin location:
Windows: C:\Program Files\Adobe\Common\Plug-ins\7.0\MediaCore
macOS: /Library/Application Support/Adobe/Common/Plug-ins/7.0/MediaCore
Let us know.
The only thing in that MediaCore folder is a file called dummy.txt - what should I try next?
At this point, I'd suggest doing a clean installation of all the Adobe apps: https://helpx.adobe.com/in/creative-cloud/kb/cc-cleaner-tool-installation-problems.html
If that does help, try launching Premiere Pro in a new user account and see how it goes.
Let us know.
I appreciate the suggestion - but I have tried that before to no avail. Frankly I'm really frustrated with this. This issue has been going on since 2014 on both Macs and PCs according to old support threads dealing with this same exact issue. I think Adobe needs to prioritize an actual fix for this to roll out for people. What would it take to assign an engineer or two this particular issue and have them thoroughly investigate it and find the cause/solution? We pay a lot of money every month for this software because we use it to make a living. But I can't use Premiere - and I desperately need to. Please - I implore you to really look into this or find someone at Adobe who can. I can't imagine that it is that difficult of an issue for the software engineers at Adobe. There is something happening with the QuickTime bundle not agreeing with the startup loading script for Premiere.
I was trying to go through the steps once more, and I noticed that my CoreSync folder located in ~/Library/Application Support/Adobe/CoreSync/ is completely missing? Why would that be?
I did a complete removal of all CC software using the cleaner tool, restart, and a clean download/installation - and the same exact problem is still happening. Can anyone fix this?
Sorry for the delay.
Would you mind contacting us on the phone or chat so that we can assist you with the help of remote sharing.
is there now a solution to the problem described? I have also been struggling with the phenomenon for a long time.
I too have just encountered this today for the first time - 10.15.7 and I was using an older version (14.9) of Premiere as I was getting beachballs reopening projects on newer versions.
Now I can't even access my project which I need to finish for a client, or even pull out an XML to take it to another NLE.
Need help urgently.
