unable to move on fabric 1.18.2

[TheKingNerd]

I don't think that the problem is the mods I installed, because they work on my single player worlds, but whenever I join, I am unable to move and any items that I get from creative are removed. I am also unable to place blocks, while OPped, and with spawn protection set to 0. Please help, because I am just trying to get my Minecraft thing to work! EDIT: Ok I can place vanilla blocks, but anything modded is a no go
