Iris 1.8.0 Beta 3 Incompatible with Skyblocker
It seems that as of beta 3 trying to load the latest Skyblocker release (1.22.0+1.21.1) alongside Iris causes the game to crash due to a mismatched local variable type in the WorldRenderer class. The previous betas worked fine. If this is an issue on Skyblocker's end let me know so that I can fix it.

Solution
This was caused by a Mixin bug that caused conflicts between our mods which is now fixed in Fabric Loader 0.16.4 :')
