ubuntu (re)start/launch problem (snap) - When ~/Documents is symlink

Describe the bug
rocketchat-desktop starts/launches once and failes all consecutive times when any of {~/Documents, ~/Pictures, ~/Music} is a symlink.

• During the first startup rocketchat creates it's config files (in my case in ~/snap/rocketchat-desktop/current/.config)
• It then failes to start UNTIL one provides a real directory (no symlink) at the ~/snap/rocketchat-desktop/current/.config/user-dirs.dirs :: XDG_* target paths
  • In my case ~/Documents (i.e. XDG_DOCUMENTS_DIR) was a symlink

To Reproduce

1. Revoke rocktechat config
   (e.g. rm -rf ~/snap/rocketchat-desktop/*)
2. Make your ~/Documents path a symlink
   (e.g. mv ~/Documents ~/Documents_moved && ln -s ~/Documents_moved ~/Documents)
3. Start rocketchat-desktop once -> everything works just fine (some minor GTK warnings, but well)
4. Close the electron app
5. Re-open rocketchat-desktop
   app closes without any output i.e. immediately with exit code (echo $?) == 1

Expected behavior
Normal startup even if XDG_DOCUMENTS_DIR is a symlin.

Additional context
Tested with all channel version today including {3.5.5, 3.0.0-develop, 3.2.2}

Ubuntu rev
VERSION="20.04.3 LTS (Focal Fossa)"

Start by reproducing the Ubuntu snap launch sequence with a symlinked ~/Documents, following the reported reset of ~/snap/rocketchat-desktop/* and the generated .config/user-dirs.dirs file. Compare the first and second launches and inspect how the XDG_DOCUMENTS_DIR target is handled. Done means the app starts normally on repeated launches when the XDG directory is a symlink.
