Hello, the workspace uses the same name I have been using for several years, throughout various versions of PS ("TJL Dual").
It is the toolbar and panels. Tab does not bring it back, only resetting "TJL Dual."
I have not reset prefs yet, but will try when I have a moment. I've noticed that I also have to reset my custom saved keyboard shortcuts at startup each time.
I should also note that Indesign's latest version is also doing the same thing... No workspace panels or toolbars showing at open. This has only begun with the most recent updates (PS 24.0 and ID 18.0), and began while I was on Monterey, and has continued after I upgraded to Ventura.
Still happening in all Adobe apps I use (Photoshop, Indesign, Illustrator). I resaved workspaces and manually reset prefs, still happening. I see that others are having issues in these apps as well since the update, so it's definitely not just me.
