game crashes when connecting to certain minigame

I go into the minigame "piyochamber" and download the resource pack and when it finishes my game crashes and gives me this error "The game crashed whilst stitching
Error: dwz: Unable to fit: Minecraft:piyo/tutorial_standard-0, size: 256x256, atlas: 8192x8192, atlasMax: 8192x8192 - Maybe try a lower resolution resource pack?"
