"Some media can't be found."

Help!

After upgrading my computer 2 weeks ago, I am continuously having problems using the Adobe Premiere Rush Application on my computer/mobile. I don't know if the fact that I swapped out a bunch of new components to my computer has caused the problem or is a conincidence, but it should be mentioned.

The current problem I face is when I upload my media files to premiere rush to edit, all the videos come through on the desktop, but my mobile app isn't syncing. I get the notification that "some media can't be found" and "missing media was imported from another device". When the creative cloud tries to sync the new files I put on to the computer, I get repeated "Unable to sync to creative cloud" notifications. The confusing part is that all of my old projects saved to the cloud are still functioning correctly, it's only the new files that I try to add since the problem started that cannot sync.

I have called the customer support hotline 6 times now in the last 2 weeks and the only responses that I get are simple, try uninstall/reinstall or turn off sync/ turn off sync; which have been no help. I'm stuck and now 2 weeks behind on my side work.
