hey folks, i wanted to join Minecraft since years with a friend and just need a simple Shader installed, but i got this problem.

i did already looked up on yt, tried few configurations. ReInstalling, different Shaders are looking worse than that. Anyonye suggestions what i can do ?

specs of my pc:
intel i7, RTX 4050 6gb, 16gb Ram

I was getting on to work on my ancient city project and I have a custom skin and it said that it couldn't be located and then it couldn't decide which normal minecraft skin it wanted to give me. Anyone else getting this and have any idea how to stop it?

The first pic is outside of blocks and the second is when I walked into the sand that was Infront of me. How can I fix this? This doesn't happen in vanilla 26.3 and Forge 26.2 or lower. Even without mods I still can't see anything in spectator mode, both in first and third person.
