I saw that with the immersive portals mod, you can either half or double your character's size with the portals. I tried this and whenever I step through the portal, my game immediately crashes. I don't know how to read bug reports or even where to start with this problem.

here is the crash report that came along with the crash:
crash-2021-08-04_19.32.12-client.txt

Anything that would be able to help me with this issue would be greatly appreciated, thank you.
