Upon launching your resource pack a lot of bugs appeared: trash-level textures, like 1x1, and missing textures (some textures work as intended), rendering the game unplayable. Could you fix it? Without your resource pack everything works fine.
P.s. I have about 250 mods and a couple of other resource packs enabled.

This might be caused by anisotropic filtering and antialiasing. Try disabling these 2. For the 1x1 textures, it was causing another issue. I'm saying was, because it was fixed on Github, but I didn't had time to properly update the TP on CF or Modrinth.
