You could actually use coin control to spend from that Bech32 address but since it's not displaying I think the wallet is not picking up the derivation path properly what you should try doing is copy the master private key and then reaccess the wallet using it. If you find that address display, get the child private key for that address and reload a new wallet with that child address. This should allow you spend exactly what's in the Bech32 address.

If this doesn't work quote me I have something else in mind that would fix it.

Just in, you are risking your privacy by searching your public key on a Blockchain explorer instead you should have loaded the wallet using your public keys.
