Unexpected Error When Creating Claim Page

When I try to publish my claim I get the following pop-up

"Something went wrong

Unexpected Error"

Checked the network tab and the get API call returns this error:

“Metadata upload error: There is ongoing metadata arweave uploads for this series”

This is actually the very first upload in this contract, and I tried switching between Goerli and Mainnet to cancel all pending txns.

Any idea what’s wrong?
