That must be a bug in how the wallet tracks the state.

Is there a button to increase the derivation path counter manually? Let's ask nostr:nprofile1qqsxn2q9vlnek6umcu5z44v42yklpwqy0prpd0kmvg7pytadgg9zvdgpr9mhxue69uhhyetvv9ujuumwdae8gtnnda3kjctv9uyzg7r2

If none of this works, you should export your wallet backup and could start a new wallet, and receive those tokens back.

Do you remember exactly what you did before this error appeared? Cheers
