Gas estimation errored with the following message ... The transaction execution will likely fail?

Question

I am trying to create my own NFT collect and getting the below erorr when compiling on Remix Ethereum.

I am using the generic TheStripesNFT solidity contract found here (https://github.com/The-Stripes-NFT/the-stripes-nft-contract/blob/main/TheStripesNFT.sol). I have only changed the parts of the contract below.

Gas estimation errored with the following message (see below). The transaction execution will likely fail. Do you want to force sending?
Internal JSON-RPC error. { "code": -32000, "message": "execution reverted" }
