I found a related post and deleting the Steam\steamapps\common\Mount & Blade II Bannerlord\Modules\Native\TileSets\pages folder and revalidating the files seems to work so far. I havent gotten the memory crash since, still need to test a few more times to make sure that or the creepy faces doesn't come back.
Edit: It ran fine the first 3 times, then it crashed again when I zoomed out fast. no faces though. I checked resource monitor and the bannerlord process has 38,318,792kb committed, which seems like it might be a little too high. The process also doesnt close out after submitting the crash report, but that may be a different bug.
