Multi-cam clips disappearing after closing and re-opening project

[PuzzledPerson]

Spent several weeks organizing, syncing and labeling mult-cam clips. Today, when opening my project file, ALL multi-cam clips are just gone. I had the originals organized in a regular bin (and sub-bins and based on the label color, delgated each clip into a search bin based on the content. The last few hours, it fluxuated between some of the clips being in both the smart bins and the regular bin and I would have to import an older project file into the new one and then all the clips would appear, though with duplicates. Now they're ALL gone.

Any similar issues going on out there? This has not happened at all in the last 3 weeks I've been working on this project. I will attach screenshots and sample screen records once people respond. Thanks.

This is consistent across auto-saved project files as well. If I open the auto-save project file, the same issue is there. Clips missing. If I import it into another project file, they are there.

Also, sometimes there is a Recovered Clip bin and the multi-cam clips that were missing appear there. But none of this is consistent. I just re-opened an auto-saved project file from 3 hours ago and there are 40 clips in the search bin. Opened another auto-save project file from last night, there are 81 clips. No clips were added between last night and today.

Where are you setting the label color - in the Timeline or the Project panel? If you're setting in the Timeline and you have Show Source Clip Name and Label enabled, this may change the label in the Project panel.

This changes EVERYTIME the project is closed and reopened

Premiere is closed and reopened.

Shutting down my computer and turning it back on.

Resetting Premiere settings

Uninstalling and reinstalling

Downgrading to another version of Premiere (went back 3 versions to 25.0 so far)

If you create a new Search Bin with Media Type set to "Sequence", do the multi-camera sequences show up?
