Hello @jordenhutch-hash, Steam calls xdg-desktop-portal to give a user-selected file chooser. The dialog box you're showing is part of that framework, not Steam itself and your issue should be reported to their maintainers. (Maybe xdg-desktop-portal-gnome?)

I also have this problem on Ubuntu 24.04.3 LTS with gnome shell 46.0

There's a workaround using steam console regardless of your operating system, here's a guide for anyone else with this problem

  1. Make sure your user has ownership and permissions to access the folder

    • sudo chown -R $USER:$USER /mnt/mydrive/SteamLibrary
    • sudo chmod -R 775 /mnt/mydrive/SteamLibrary

  2. Open the steam console using this url steam://open/console

  3. Use this command in the steam console to add the directory or drive you want

    • library_folder_add "/mnt/mydrive/SteamLibrary"

The directory or drive should show up in the settings under storage
