Seeing sky color everytime I join a realm

[Molang][error]-minecraft:player.0.xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx.CustomSlim1ca8805b818a4e918e8a587f203fc6d4 | trying to set variable 'variable.tcos0' to #nan/#inf! setting to zero instead

I am trying to join a friend's survival realm, I cannot see any terrain but the sky color. I can see my avatar, I can see my inventory, I can chat, I can see my heart and hunger bars, and hotbar.

My friends also said that everytime I get disconnected the realm crashes and rolls back some time.
