Error: Could not complete the command because the file could not be found.

Good morning,
I have a problem with Photoshop. I accidentally uninstalled the program probably in 2020 version and quickly reinstalled it in version 2021. When I try to open the program I get the error "Could not complete the command because the file could not be found." and then "Could not initialize Photoshop because the file could not be found". Sorry for my English, I used google translator for the above mentioned errors.

Thanks for help.
