I have figured the work around for this back in December already - in it I would open another Xcode project and then with the project window open, I would open the needed project with File - Open Recent.
Here's a funny thing: today, that OTHER project has stopped opening too. Amazing.
Now I'm using a third, different project, and apparently I'm running out, but statistically, I'll lose access to all of them only by 2023. Amazing.
