I was tweaking some things in my modpack, and suddenly when when I wanted to try it out this happened.

-- MOD backpacked --
Details:
Mod File: backpacked-1.9.0-1.16.3.jar
Failure message: Mod backpacked only supports curios 4.0.1.0 or above
Currently, curios is 1.16.5-4.0.5.1
Mod Version: 1.9.0
Mod Issue URL: NOT PROVIDED
Exception message: MISSING EXCEPTION MESSAGE

if I'm not mistaken, my curios version is higher than what backpacked is asking for. I made sure to download the latest version for both mods, pero it still happens. Full crash report down below.
