Many Items are invisible. But I have Sodium + Indium installed, what is going wrong?

I tought it is because of Immersive Portals, but now I've removed it and the problem is still there.

No idea. Certainly an issue with another mod, but I have no idea which one it is. Could also be a configuration issue with indium.

thanks I will try to figure it out.
Indium Config is default:

#Indium properties file
#Wed Jun 29 16:08:43 CEST 2022
debug-compare-lighting=auto
fix-exterior-vertex-lighting=auto
ambient-occlusion-mode=auto
always-tesselate-blocks=auto
fix-smooth-lighting-offset=auto
fix-luminous-block-ambient-occlusion=auto
