Please describe your issue in as much detail as possible:

Steam opens right click -> Manage -> Browse local files in Visual Studio Code instead of Nautilus.
For some reason, Steam (native) started seeing Visual Studio Code (flatpak) as the file manager program.
This happens in both stable and beta.

It also happens when going to settings - storage, then browsing from there, and it happens in big picture mode too.

Steps for reproducing this issue:

1. Right click on a game in library
2. Click "Manage"
3. Click "Browse local folders"

or

1. Click Steam menu
2. Click Settings
3. Got to Storage
4. Click the ... icon, then Browse
