Update completely deleted all my preferences, presets, plugins, workspaces, etc.

I was already running Photoshop 26 (not sure which build number, but I think 27.10) For some reason the Creative Cloud app was acting as if Photoshop was not installed on my machine even though it was.  Photoshop was not included in “Installed on this machine” under “Your Apps” and it would not auto-update. I waited weeks hoping it would resolve itself, and then finally just went and installed 27.11 manually (I had to click “Install” down under “Featured apps in your plan” instead of the usual “Update” towards the top.)

But now, all my presets, preferences, plugins, actions, workspaces, brushes, patterns, gradients, swatches, etc. from my previous version are completely gone. And there's only one "Adobe Photoshop 2026 Settings" folder and only one "Adobe Photoshop 2026" apllication folder, so it’s not like I can access the previous files to manually migrate.

And yes, I’ve always had “Import previous settings and preferences” checked, but I think CC treated this as a new install instead of an update for some reason.

This is absolutely DEVASTATING to my daily workflow, and to start over would be a massive setback. So PLEASE someone tell me there’s something I can do. Thank you.
