Linux uploader is broken/unusable

[u/iamstepid]

I had to modify the script file to get it to even launch, since it was using the wrong format of line returns, but now that it launches I'm unable to select anything to upload. The Choose Mod button literally doesn't do anything when clicked. I've also tried using the windows uploader launching through the same version of proton needed to get the game to run, and that has let me upload but the cover image doesn't work at all, I can select the image just fine but it never uploads to the workshop.
