Hey, I read your comment on my last issue, I updated the mod to 1.9.1 but now it gives this error:

MineMenu (minemenu) encountered an error during the sided_setup event phase
java.lang.RuntimeException: Ran into an issue regarding reflection with field f_90818_ from

this is the only mod I'm running (I can't remember if there are any mod dependencies)

I'm also running 1.17.1 to answer your last question
