Weird glitched terrain with a gap

Found this weird glitched terrain in this zone in act 2 of the game after slaying the void worm thingy and traveling to the ancient caverns in the past. I was playing on online mode as a rogue, my pc specs are RTX 2060 SUPER, Ryzen 5 3600, 16Gb DDR4 RAM and a 480 SATA SSD, Windows 11 with up to date drivers. My pc runs fine in all other games and I never encountered a bugged terrain with a gap like this or in this area before. This is my first online character to make it out of act 1.

Bumping, same issue here. GTX 1060 6gb, Ryzen 5 5600X, Windows 10, most settings on medium, terrain on high. Tried changing various settings to see if it would fix itself, no luck.
