Navigate to this folder. Note you need to make Hidden Items viewable under the File Explorer > View menu.
C:\Users\[your user name]\AppData\Roaming\Adobe\Adobe Photoshop 2022\Presets\Brushes
You could try renaming the Brushes folder to something else like suspect_brushes
Now try starting Photoshop. What happened when I tested this is the first time I clicked to open it didn't open, but it remade a Brushes folder. The second time I clicked to open Photoshop it opened OK, but the folder was obviously empty.
If you do this and Photoshop starts OK, then you probably have a corrupted .abr file
Hmmm... Hold that thought. As you can see below, the brush presets fold is empty but Photoshop still has all the .abr files.
It might have loaded them from the previous version, which you can see is still there. Give this a try all the same, and if it does work, then try copying the .abr files fropm the previous version as they will probably be OK. For goodness sake back it up first by saving it to another folder.
