Minecraft wont load if the FabricAPI is installed

[NotEski]

every time I try to load Minecraft if I have the fabric API in the mod folder with any version of Optifine the game won't load if Optifine is not in there and just Optifabric the game loads up but displays the "Optifine is not present screen". I don't know this code very well but maybe haveing a different folder for the optifine.jar or parsing the version folder that Optifine makes.
