I just got around to updating all of my mods to their final 1.18.2 versions, and that required me updating both my fabric loader and iris as well, so I just used the most recent fabric file, 0.14.14 and created the new profile for the 1.18.2 version. I then did the same thing with iris.

I'm now getting this error message on startup and I don't know enough about coding to understand this since it isn't giving clear indicators as to what's wrong- is anyone able to help?

A mod crashed on startup!

👋 We use the issue tracker exclusively for final bug reports and feature requests. However, this issue appears to be better suited for either a discussion thread, or a message on our discord server. Please post your request on one of these, and the conversation can continue there.

Please ensure all mods are for Fabric 1.18.2. I think you have mods for other platform in it.

Ah! Yes! Thank you so much, oh my god lol

Apparently OKZoomer changed into a quilt mod and the file name wasn't changed; spent like 2 hours troubleshooting my mods individually

phew, again thank you, wouldn't have figured that out otherwise
