No matter what version of FabricAPI or optifabric I use, worlds will get to 100% loaded and then freeze. FabricAPI versions 0.54.0 and up and optifabric 1.13.0 and up are ones that I tested. Error logs always look the same. FabricAPI on its own will load fine, as well as optifabric and optifine on their own, but something goes wrong with all 3.

Try Fabric API 0.58.0+1.18.2 + OptiFabric 1.13.10 + OptiFine 1.18.2 HD U H7.

That combination has been working fine for me.

I don't use 1.13.10, It crashes for me, I use 1.13.8, with HD U H8 and works fine. Same modlist with 13.10 crashes on launch
