Sorry to hear that you are facing this issue. Can you please check layer options dialog?
From panel flyout open Layer Options and see if the thumnails for “Layers” “Groups” and “Objects” are selected and “Top Layer Only” is Not selected.
Also “Show Layers Only” check box should be deselected.
let me know if this solves your problem or not?

Update (within 20 minutes of posting this):
Started a new project to see if layers panel would corporate. It did. Didn't close out my old one as I did this. Checked back into old project, and pleasant surprise, the layers panel on the old project running again as usual.
Very bizarre. Seems buggish for sure.Brooke Wunderley shared this idea ·
