Crash log as requested:
crash-2022-10-23_09.15.32-client.txt

It's highly probable that this mod is not causing the issues that I initially thought, as there were crashes after the case which logs stated were something else entirely. It's possible that another mod is/was causing an issue between others; here's the log that was generated roughly 20 minutes later from the above log:
crash-2022-10-23_09.37.15-client.txt

Update Geckolib.
