I am using Ubuntu 22.04.1 LTS. Recently, when I try to open files from any application such as inkscape or firefox, it appears the application is unable to access the file dialog.
For example, when I try to download files using firefox and select save in a different location, the file dialog doesn't show up.
In inkscape, when I try to open existing files, the file dialog doesn't show up.
Please comment if you have faced a similar problem or have some clues about how to fix it.
