Black floor glitch and hole in floor glitch

I’ve been playing infinite flight a while now and have recently had frustrating issues with the terrain.

Firstly there was an issue where the scenery didn’t load and there was infinite blackness so I reinstalled the game but soon after it happened again so I did the same.

Now there is a glitch where I fall through the ground. It happened first whilst taxiing and now i can’t even play because I keep falling through the ground. Since I’ve alresdy reinstalled the game twice I don’t know what to do.

Is there anything else I can do
