Avatar Note Uploading

So, recently won a package from a giveway, went to upload it and got these errors. Instead of uploading it just creates a new prefab and doesn’t work.

That error often pops up because of compiler errors, once those are solved the FileNotFound error will go away. (usually)

The errors you’re showing us doesn’t tell us much.
Ideally upload a picture of the console when these settings have been applied to it.
