Not available for Fabric 0.14.21 (Minecraft 1.20.1) ?

Is there a way to make Iris Shader work for Minecraft 1.20.1 for Fabric loader 0.14.21 ? It crashes instantly, and there is no visible error code. (I am making a modpack on Modrinth, and thought it was an incompability issue, but removing every other mod/ just keepking fabric API and Sodium doesn't seem to work)
Thank you in advance for your help
