The answer
Wallets may use different address families such as legacy, SegWit or Taproot, or different derivation paths and account indexes. A missing passphrase also changes the entire wallet.
What to do next
Check the original public address prefix and original wallet software. Restore the intended account type and compare a known historical address.
