Not entirely sure what is happening, maybe someone can help?

The same problem

One of the jar files seems to have had an issue, I'd redownload the mods again to see if that fixes it.

I have redownloaded but the problem persists

oops

What is your fabric api version and fabric loader version ?
And what launcher are you using ?
Also due to #1016 what drive are you using to run fabric on ?

I did something and it works now, I changed some files so I can't say for sure what API, loader, or launcher I was using.
I do have an SSD (my main drive) running fabric.

I'm quite sure that the fact it's SSD is not the problem.
But well, if it works now, it may be closed.

Closing due to lack of feedback, if this is still an issue, please make a new issue.

Since this seems to be an issue with ZIP end header not found, maybe your Antivirus could be corrupting the zip file?
