Access to path is denied

I can't save my progress because of "Access to path is denied." error.

I renamed the SDL folders in AppData "Local" and "Roaming" and got "Service Sdl.TranslationStudio.Api.ProjectManagementService could not be started." error

I also uninstalled and reinstalled SDL Trados Studio.

Trying to change any options also gives "Access to path is denied." error.
