Stuck in Iona's Cavern

EDIT: Restarted the game and bug seems to have vanished, allowing me to finish the climb. Very strange.

I’m unable to climb to the top of this ledge. When I reach the top my character stands up but can not move forwarding, acting as though there was an invisible wall blocking their progress. I can’t roll forward or out of the way and the two guards on the ledge inevitably knock me to my death.

I’ve repeated this process 7-8 times, attempting to go as fast as possible, but it’s as if I’m being body blocked no matter how fast I climb or where I am on the vine ladder.

This is my second playthrough and had no issue in this spot, but this play through I’m only level 9 and I don’t remember these same guards being in this spot on my first play-through.
