I had a similar issue and none of the responses worked for me. I tried something new that worked for my short Instagram sequence, but did not work for my full length multicam sequence.

This is how I fixed the short Instagram sequence: Without any in’s and outs, I highlighted all of the assets in the sequence and I exported as an xml.
I imported the new xml and it worked, the clips were restored!

I still haven’t found a way to fix my multicam sequence, so I am just making a new sequence and resyncing it all. Luckily I hadn’t started working on that one yet. I feel like it is a separate issue because in my multicam sequence all of the clips have the lines at the end of them. The short one minute Instagram sequence only had three clips with the issue. However, I did notice a difference in the clips. In the Instagram sequence, the diagonal lines went through the full clip it was on. In the long multicam sequence it only went through the ends or part of the clips.

Hope this helps! If anyone knows of another way, please share.
