i keep on getting this error message when i open mc with universalmodcore. but if i remove it. the error randomly goes away. how do i fix this? any answer is greatly appreciated! btw the crash file is right there -> (https://github.com/user-attachments/files/21113655/crash-2025-07-07_22.52.32-client.txt)

also btw if ur wondering what version of mc i use 1.12.2
java version: version 8 (build 1.8.0_451-b10)
forge version: version 14.23.5.2859
EDIT 2!: So when i opened minecraft WITH ONLY Universal mod core. it worked. but when i paired it with immersive railroading. it stops working. i assume its because of immersive railroading. because i left track api open and it worked just fine

Could you delete all config files and try again?
