I was able to confirm that this error starts after completing the rune. i started a new save and as soon as finished the rune it started to crash before it was working fine. were you guys able to find out anything on why this is happening or still no clue?

Yeah it does have something to do with the view distance; I created a new save with medium view distance then completed the ruin and it crashed, I loaded up the same save without changing anything to confirm that the error is happening and it crashed again. I then changed the view distance to epic and Malo spawned in just fine and no crash.
