TOPIC: Help with alt.

So i bought an alt for gmod so i can transfer some items, but when i try to boot garry's mod on alt (steam client running on sandboxie) The game just opens and closes. Whilst the game on main (not in sandboxie) keeps running. any help?

Update: Now when i try to boot steam in sandboxie it goes stuck on updating.

sandboxie doesn't work with Garry's Mod on Windows 10 with anniversary update, rollback before the update (at least that's for me)
