Media offline with no file path in former team project
I just opened a project file that was working fine last night to see that all of the media in it are listed as "Offline: File Missing" with no file path whatsoever.
This is a former team project converted back into a regular project, which until today has had no file-linking issues since the conversion a week or two ago. I suspect the file path has become distorted due to this project's former life as a team project, since team projects appear to use a cloud-based media path versus a local one.
The following message is listed at the bottom left of Premiere:

There are over 7,000 assets in this project, so relinking them manually would be devastating. Any help would be so insanely appreciated.
I'm using PP CC Version 12.1.1 (Build 10) on a Mac Pro (Late 2013), OS High Sierra Version 10.13.5.
