I could not use Photoshop properly for months - without the keyboard shortcuts working. Imagine not having ctrl-z??? Or any other shortcut.
Last night I wasted 5 hours removing all Adobe and reinstalling a few times and cleaning with Adobes DOS tool for this. And piles of other stuff googling for solutions. With no luck.
Now it seems I found a workaround and in some way a hint for solving the problem? As I am Danish I use a Danish keyboard layout (English being the language for the PC, not Danish). Changing to English / English makes the shortcuts come back.
How to make it work with my Danish keyboard also? Previously it worked for like 20 years, so I know it is possible :-)
We have a few more letters in Danish, but also most special characters are in different places than on an English keyboard, so keeping English / English is not a solution.
Illustrator and other Adobe apps never showed this problem.Different physical keyboards also did not change anything.
My Win 10 is Version 10.0.18362 Build 18362...
My physical keyboard on my Huawei laptop is "Nordic" (two keys change letters between three languages), the other two keyboards I use are Danish Apple numeric keyboards, one USB wired, one bluetooth.
