Does anyone know how to fix this?

I’ve been trying to publish this asset for a day now, but it doesnt work at all.

Everytime I try to use the plugin “Animation Spoofer” to fix my game animations, this shows up when i try to publish them.

I’ve tried looking on youtube and all over the devfourm.

And Yes, I know this belongs in #bug-reports:studio-bugs, but I cant post in there.
