Fabric/Fabric API installation error

[Violets]

I am trying to install Fabric 1.19.3 in MC Launcher (not through MultiMc etc.) however I got error and unable to launch it.
After I fiddle around, this is what I notice:
- Installation of fabric loader was fine, I am able to launch it without any .jar file in mods folder.
- I then drag in my mods .jar file (modmenu, inventorytabs, shulkerboxtooltip, etc.), WITHOUT fabric-api.jar, upon launching the game prompts me to "Install fabric, version 0.55.3 or later."
- I then add on fabric-api-0.76.0+1.19.3.jar and try to launch. The game crashed whilst initializing game with "Error: java.lang.RuntimeException: Mixin transformation of net.minecraft.class_761 failed". Crash report: https://pastebin.com/MhN9VZu2
- Replacing to FabricAPI of 1.19.4 and older 1.19.3 version doesn't help

I tried launching with MultiMC and it crashed. I then disable FabricAPI and this are the errors. Seems like fabric is the one problematic on my end.


Incompatible mod set!
net.fabricmc.loader.impl.FormattedException: Mod resolution encountered an incompatible mod set!
A potential solution has been determined:
     - Install fabric, version 0.55.3 or later.
     - Install fabric-api, any version.
Unmet dependency listing:
     - Mod 'Freecam' (freecam) 1.1.6 requires any version of fabric, which is missing!
     - Mod 'Inventory Tabs' (inventorytabs) 0.8.1-1.19.x requires version 0.55.3 or later of fabric, which is missing!
     - Mod 'ItemSwapper' (itemswapper) 0.3.2-mc1.19.3 requires any version of fabric-api, which is missing!

Issue resolved. I did a trial an error and looks like the freecam mod is the problematic one. Idk if it really is the source of the problem but it works now so..

For future reference, we are not Fabric. Fabric does have their own support channel if you want to google it.
