If that doesn't work, you can try using the WalletConnect option to connect your MetaMask wallet. To do this, open the WalletConnect app, then click the MetaMask option. You may also need to make sure you have the correct network selected in your MetaMask wallet. If you are still having difficulty, it is best to contact the MetaMask support team for further assistance.
