In versions before 1.20.5 I used this mod and also used a mod called AutoHUD, they both are technically uncompatible but only because AutoHUD has a feature where it dynamically hides the potion effects icons, but it can't hide the bar that this mod adds. I never wanted that feature, so I just kept it disabled and I didn't have any problems or crashes, but when I updated to 1.20.6 Minecraft crashed every time i had a potion effect due to a mixin conflict between AutoHUD and this mod. As I said early this never happened when I was using MC 1.20.4.
