Try adding
mixin.entity.collisions.movement=false
to the lithium.properties file in the config folder

i added it but it didnt seem to work unless i added it wrong

You added it correctly, but you need to post another crash report

Can you test whether this issue occurs when you change nothing besides removing lithium from the mods folder?

I'd give one but it doesn't generate one for me, which is strange (this is after added the line to the config)
this is all it gives.

Yep, with lithium removed, there is no crashes, only issue is, this modpack I'm using is dependent on lithium (I have no idea how it didn't crash)

(except it does crash when loading a world, so yes, it is dependent)
Nevermind, it doesnt crash

(except it does crash when loading a world, so yes, it is dependent)
Nevermind, it doesnt crash

Okay so it wasn't a dependent but the server owner still wishes to keep lithium,
Ive tested around fully and yes the crash is only with lithium and with the gravity mod in.

I have this same problem, and I tried to use the config fix, but it didn't work. Here is the log.
latest.log
I only ran Gravity Changer, Fabric API, Cloth Config, and Lithium, all the latest versions in Minecraft 1.18.1.

Add mixin.entity.collisions.suffocation=false to the lithium config.

Mod authors can automatically disable this mixin as well. https://github.com/CaffeineMC/lithium-fabric/wiki/Disabling-Lithium's-Mixins-using-your-mod's-fabric-mod.json
