Game Freezing After Host Disconnection

[Nayibmc]

Hello.
I know my PC is old, but have an NVidia GPU and the problem I'm gonna talk about doesn't seem to caused by my PC's performance.
Whenever I'm doing a bounty, or Operation Plague Star, if the host disconnects (which always happens, doesn't matter whether I get to the door first), as soon as the game displays the ship loading screen, it freezes for at least 2 minutes, and then it starts loading correctly as always (but failing everytime at the host migration if I'm on the Plains, not on any other non-Plains mission, though).
So I actually have three problems:
1. Always getting a host migration when a mission on the Plains is finished
1. Game freezing after host disconnection
2. Game never able to do the host migration if I'm on the Plains of Eidolon
