@dyiing Well I actually got it working.. 
for anyone interested how:
I swapped the sodium version to this:
sodium-fabric-mc1.18.1-0.4.0-alpha6+build.14
and am using this version of IRIS:
iris-mc1.18.1-1.1.5
and it works fine...other than one side issue... Lithium will
not function with this pairing apparently.
@dyiing No im using 1.18.1 and the error im getting is it keeps saying the IRIS and Sodium dont match or are incompatible
Ive been trying to add IRIS to my Aristois.. but i cant seem to find a version of IRIS and sodium that seem compatible with it.. is there a particular version of these that work well with Aristois? When I attempt to add Iris my game immediately crashes up logging into a server.
Im using MC 1.18
