I have grid-1.19.3-fabric0.68.1-1.6.7 with Fabric 0.14.18 in Minecraft 1.19.4. I'm able to start the game and load a world, and I can use the mod's functions with commands, but when I try to open the mod's menu with the keybind, the game crashes. I usually use other mods, but I temporarily ran in with just Fabric and Grid to see if there was a conflict, and it still crashed.

Happening to me too;
Minecraft: 1.19.4
Loader: Fabric 0.14.19
Grid: 1.19.3-fabric0.68.1-1.6.7

yes, 1.19.3 screens don't work in 1.19.4. There's a 1.20 version now that has a working config again.
