I've seen post about this being a permissions issue commonly related to work computers etc... but i can assure you its not a permissions issue on my side. this is a perosnal computer, ive been dealing with this issue across 3 different computers since ive had photoshop over the last 10 years or so. I'm just sick and tired of it at this point. every now and then all my shortcuts just get set to default. no major update was done. heck sometimes no update was done at all. all my keyboard shortcuts just go away and i have spend the next hour or so hunting down what i used becuase everything i did is off muscle memory. i tried saving my shortcuts and reloading them everytime it happens by appending the previous (deafults) but the saved shortcut files dont do anything. moment it says are you sure you want to rewrite previous files, it thinks for alittle bit as if its loading my shortcuts in but nothing. Adobe this is getting incredibly frustrating, at one point you even compensated me for this issue so i know its an issue on your end. this needs to be fixed now!
im a windows user if that makes any difference
