Gas estimation failed when call Mint Function on remix

Question

I'm experiencing some difficulty conveying my NFT minting smart contract on remix to test it. I've followed all the possile method found online. i tried by changing different values for minting cost and msg.value but notin is work well. contract deployed witout any error,but issues is with mint function.

contract deployed on rinkeby succesfully, but when I call Mint function, getting Gas Estimation Failed error.

I tried all possible way to resolve. unfortunately, not get it done.
