OptiFine HD U H9 was built with Forge 43.1.1 and even OptiFine HD U I1 pre4 is only built with 43.1.52. I know of one breaking change with the push command. So pretty much optifine needs to release another version for 43.1.57 This was a small fix I had to modify the mods to work in optifine.

Which file is the one you have modified and from which mod? I searched in the IC2 classic repo but I can't find it.

@SamuX99 This was the related mod shown in the screenshot. https://github.com/BluSunrize/ImmersiveEngineering/blob/86211504ad15b866e6df4685eb16c239cd6f16bb/src/main/java/blusunrize/immersiveengineering/client/render/IEOBJItemRenderer.java#L102

I think this was the forge update that breaks when optifine overrides the mods forge version. https://github.com/MinecraftForge/MinecraftForge/pull/9083

OptiFine on 1.19.2 is still broken. Some mods are not available for 1.20 yet, so I'm stuck there while playing with my daughter. Have you found any fixes?
