I just installed quark in 1.16.3.
When I go into a server or singleplayer, I go in, I see the world during a second (without being able to move because of the lag) and then the game crash instantly.
After this I got this message:

The game crashed whilst rendering entity in world
Error: java.lang.NoSuchFieldError: renderOverlayEyes
Code de sortie : -1

Ok thanks

Looks to be an issue with Optifine; there is unfortunately nothing we can do on our end.

It worked, i wasn't playing with Optifine but I had Optifine 1.15 and 1.16.2 in my files so i deleted it.
