Im not fully sure what the issue is, and it's not that big of a deal, but the mod is overloading my log files and multimc isnt happy about it.

Reset your DynamicCrosshair config file.

This didnt fix it sadly

Oh, I missed that you were on 1.19.2. That must have been broken forever, I wonder why nobody ever mentioned anything.

Until I can push out a fix, you can fix it manually by going into the config file, and changing the null to "" (empty string) for the "additional*" entries at the bottom.
The end of the file should look like this:

…
	"additionalTools": "",
	"additionalMeleeWeapons": "",
	"additionalRangedWeapons": "",
	"additionalThrowables": "",
	"additionalUsableItems": "",
	"additionalInteractableBlocks": ""
}

Ohhhh gotcha, my bad, that fixed it then, thank you!

This fixed the errors but the crosshair is like not fully disappearing now

Because you have a shield equipped.
