@ramsesthe7th You need to download optifabric and optifine and put optifabric in .minecraft/libraries/me/deftware/EMC-f-v2/latest-1.17/ and then put optifine in .minecraft/mods/ and it should work, do note that there probably will be bugs which are currently trying to be fixed and other things that will happen.
