Having the same issue here... I tried to move a double-row sized widget onto my 2nd page of apps and the whole Home Screen edit view just crashed and I got a spinning white wheel on a black background.
When the wheel finished spinning Home Screen layout was destroyed, all folders (except for like 2 randomly) wiped out, and apps now spread out across like 8+ pages when I only had 4 total originally!
Has anyone determined a fix for this yet? I’m thinking about wiping/restoring from a backup, but I just really don’t feel like going thru all that hassle just to get my views back... I feel like maybe this is an Easter Egg bug designed to force power users w/ a lot of apps to use the new App Library lol 😂!
