[BorisIsActuallyBOBIIII]

My game always crashes whilst loading. this is the crash report:
The game crashed whilst rendering overlay
Error: n: Non [a-z0-9/._-] character in path of location: minecraft:block/sword_custom/Texture

I'm not exactly sure of your exact problem. But make sure you're using Optifine 1.13.2 and have Java Installed, that's the main thing, if not, try reinstalling your entire Minecraft, that could help.

That happens when you try and join the server with the texture pack enabled and no optifine. You should use optifine. Preferably 1.13.2 although other versions are fine it's just what we reccomend.
