But does it work without Iris or not? If it is working without Iris then it may refer to an issue with system hardware or different video settings net.minecraft.client.renderer.LevelRenderer.handler$zkm000$sodium$renderClouds It may be caused by rendering clouds - so try other settings for clouds or disable these

Replace it with this build: https://www.curseforge.com/minecraft/mc-mods/lendercataclysm/files/6331219
