The other day while uploading my newest version of my UAC Asset, Got this Error while Unity was sending it to the AssetStore for review:
Error Uploading Assets: An error ocurred during assets upload
Please retry. Error receiving response from server
(-1): The object was used after being disposed.
Simply tried the upload again… Same thing.
Closed Out of Unity, and Re-opened with a blank scene. Worked this time.
Try it out! Does it work for you?
Hope this Unity3d.Expert solution has saved your day!
