Using PS 2021 v22.1 I have lost all my presets
Yesterday 2021/22.1 froze and I had to force restart my machine. When starting up again PS was telling me my Gradient map was corrupt/bad. Looking more deeply I note that ALL my presets have gone. I have looked in User/appdata/roaming/presets and it is empty as is virtually every folder under presets. I have looked my PS 2019 folder and it is the same.
I have uninstalled PS2021 and rinstalled with no effect.
I have the same setup on a laptop, but on that I can't find User/Appdata at all! The laptop is working OK.
HELP .. please.
Using Windows 10 (latest update).
