The current implementation removes the support of ERC721Enumerable for the NextGenCore contract, as super.supportsInterface(interfaceId) will return the supported interface of the rightmost overridden contract, which is ERC2981.
This will break any possible integration that expects the contract to support the interface of ERC721Enumerable, including the NFT interface for ERC721. This could be for example an NFT lending protocol that expects the NFT contract supports it (in this case NextGenCore).
NextGenCore.sol#L337-L339
Add the contract support for the ERC721Enumerable interface in supportsInterface().
