Texture pack x256 always crash game. Impossible to set lower resolution on Realms

Game always crash when trying to load with a texture pack of x256. On realms, I can't set it lower to x128 as it seems to always reset itself to maximum resolution (x256). x128 packs works 1 time out of 3 (like ChromaHills). VanillaBD is the pack I'm trying to use. Works fine at x128 on regular worlds but not x256. Impossible to load on realms as it always set the resolution back to x256. I'm playing on my PS5, and tried it on my PS4 Pro, both are not working. Thanks.
