No matter what mod do i use it just crash
I tried installing only OptiFabric and Optifine and it worked but whenever i add any mod it crashes instantly
That just kills the point of using fabric for me, if i can't install other mods why am i using OptiFabric to begin with?

What mods are you trying to use? What are the version of those mods? Also what version of MC are you trying to play? If you can provide an error or crash log that would help to.

Mods i tried but didn't work:

• JourneyMap 1.20.4-5.9.21
• Mouse Tweaks 1.20-2.25
• Jade 1.20.4
• Provi's Health Bars 1.2.4

all of the mods above works perfectly on 1.20.4 without using OptiFabric

here is a picture when it crashes, i get different crash message depends on the mods i try to use

Fabric Loader 0.15.6, Optifabric 1.14.3, Journey Map 1.20.4-5.9.21-fabric, and preview_OptiFine_1.20.4_HD_U_I7_pre2 all work just fine. Using any of the newer Optifine Jar files will result in that error. Also it is Provi's Health Bars 1.2.4 that is causing the conflict and erroring out. All of your mods with what I said at the beginning will work without Provi's. If you are in need of health bars then may I suggest using Toros Health bars instead.

Not sure if this could cause the issue but i use CurseForge to install all my mods
i can't seem to find "OptiFine HD U I7 pre2" there is only "OptiFine HD U I8 pre2"
I8 not I7, I tested with "OptiFine HD U I7", is it possible to share the link here for the OptiFine HD U I7 pre2 ?

I will upload and host it so that you can grab it. https://www.mediafire.com/file/tyk30u6yxele2z1/preview_OptiFine_1.20.4_HD_U_I7_pre2.jar/file

Yeah seems that that version was removed since they have the working full version.
