Basically as shown in the below video, I cannot use the editor anymore, because it keeps spamming that message popup, which if I could use the editor I would fix by replacing the now null sprite image references…

This happened after I deleted a few sprites, which I was going to replace(the new versions are already sliced and put into animation clips)
Using Unity version 2019.3.10f1
If I need to revert to my last commit, its a not a big deal, but wastes about an hour of work, so I’ll wait to see if anyone knows a solution.
Resurrecting this thread to say force quitting seems to be the only option and it’s obviously terrible. I’ve just lost an hour of work because this lovely popup does not go away.
