If you are playing with version 1.21 then try switching to 1.20.4 or lower.
Opls doesnt completely support 1.21 specifically custom potions dont.
1.20.4 should work

You get kicked when you get any custom effect in 1.21. There maybe any custom potion in dispencer.
If not I dont know more. But 1.20.4 should work fine.
