Did a bit of poking around to find the root cause. Turns out Immersive Portals is nuking an entire method that Satin injects into. This is entirely on Immersive Portals and isn't something I (or Satin, for the most part) can fix. Thank you for the report!

edit: to clarify/summarize, this is an incompatibility between Immersive Portals and Satin (a mod I depend on), and it is not Satin's fault.
