If you open up the project editor and click on the project name on the top left (or at least where it’s supposed to appear), the editor page goes blank!
Browser - Firefox
Version - 88.0.1 (64-bit)
I was also able to reproduce this on Chrome [version 91.0.4472.77 (Official Build) (64-bit)] as well.
An ideal way to fix this would be to show an error message instead of going blank.
Also for those who wish to know why you would want to click on the project name area so fast without waiting for the editor to fully load, this happens when you remix the wrong Express starter and you want to archive before wasting anymore time.
