No error message appears, no help. What could I do?

This is a (wanted) limitation of the home interface, it does not allow access to hidden directories… you can either make the dir visible by removing the leading dot from the name or ask the snap maintainer to port the snap to use xdg-portals which provide file access through a proxy mechanism and through that allow access to hidden directories and files

Another option is to use personal-files : The personal-files interface
