Mystical Ag wont work in botany pots minecraft forge 1.20.1

i am having a issue with a mystical ag not working in botany pots. i have added both mystical and pots to the modpack i am playing along with a few others. it doesnt crash and runs fine. i just cannot put anything into pots. not even normal minecraft items like wheat seeds or even a sapling. theres a 'affinities: unknown' when i try shift clicking it into the pot. i have never had any issue with pots before so i have no idea what could be causing the issue. i have tried everything i could think of and the issue is still there. if anyone could help itd be greatly appreciated for as i want to pay this pack for a long while.

java.util.ConcurrentModificationException: null - Exception in server tick loop

Hmm these are server build issues - autocomplete works on paper

So the worldedit issues may be referring to the Ketting server build

FAWE doesn't show any autocompletion of blocks names and there are errors needing me to reload chunks to see the edits. It obviously won't be a definitive solution.

2 Weeks ago i got a new laptop and installed on it curseforge and normal minecraft and java, and wanted initialy to test how some modpacks would run to then start a new world to play when i had time.
Fresh windows 11 install, i wouldn't think anything could happen but bam error -1073741819, and i can't find any way to remedy this. I reinstalled java, updated drivers, reinstalled minecraft, launchers, even prism launcher, tried eclipse temurium instead of normal java... nothing seems to work
