Hey, i wanna use optifine, fabric, and replay mod. But Optifabric didn't work, i read #511 , optifine work without replay mod. My mods is Modmenu, optifabric, optifine, and replay mod. (Modmenu didn't give problems, i test him before)

currently, optifabric does not work on 1.18.1 with the fabric API so the replay mod won't work yet cuz the replay mod requires the fabric API

"replay mod won't work yet cuz the replay mod requires the fabric API"
I can run replay mod on fabric without fabric API
and I can run optifabric with the fabric api

(x = its enabled)

This config works

Fabric API [X]
Optifabric [X]
OptiFine [X]
Replay Mod [ ]

This config works

Fabric API [ ]
Optifabric [ ]
OptiFine [ ]
Replay Mod [X]

This config DOSENT work

Fabric API [X]
Optifabric [X]
OptiFine [X]
Replay Mod [ X]

EDIT
I am using MultiMC 5
And I loaded fabric into a version
So might fabric api just exist in there even though I dont have it put in the loader mods?

^I have this same issue

same problem here.
OptiFabric + Fabric-API without replaymod = load the game
replaymod + Fabric-API without OptiFabric = load the game
but OptiFabric + replaymod = crash while loading
