Latest version of parcool crashes with this mod due to a missing mixin

[Orifan1]

how to reproduce: try to run an instance of minecraft with both this mod and parcool installed. (found here: https://modrinth.com/mod/parcool)

on further research it seems to be something parcool changed in its 4.0 release, as the game works fine on the last 3.X version, but crashes on the earliest 4.0 version.
