Description

Hello.

Trying to launch minecraft Fabric 1.21.4 for the first time. Keep getting an error message from the launcher.
This error advises me to install fabricloader 0.16.10:

"A potential solution has been determined, this may resolve your problem:
- Replace mod 'Fabric Loader' (fabricloader) 0.16.9 with version 0.16.10 or later."

But... It's already installed. It seems it still loads through 0.16.9?
I even uninstalled my launcher and made a clear installation, then downloaded and installed fabricloader 1.16.10 for 1.21.4 in recommended direction several times with no success (i didn't change anything, here's the screenshot). I also have the latest version of Fabric API.

I see the log says the "ModernFix" mod is not compatible with 1.16.9 and requires 1.16.10, but why is this still an error when i installed a fresh new 1.16.10 fabricloader? and other mods are NOT affected at all. When removing "ModernFix" mod, game launches fine.

Can you explain me what's the problem here?

I hope i explained my problem well enough as English is not my first language. Please read carefully and no hate, i'm not good in understanding this kind of things.

In Minecraft Launcher edit the Fabric Installation and then change its version to the one you just installed.

how do i do that?

my laucher is TLauncher legacy, version currently selected is Fabric 1.21.4.
i see there is "release fabric-loader-0.16.10-1.21.4" - is that what i need? it's without TL logo, though.

TLauncher is piracy and is not supported as it violates several laws and user agreements
