If you don't care much about the privacy of all your wallet's addresses you can enter the
Account Extended Public Key in the search field of the blockchain explorer
https://bitcoinexplorer.org. It will display both external (receive) and internal (change) addresses and their balances.
Account Extended Public Key according to
https://iancoleman.io/bip39/. bitcoinexplorer.org understands to derive addresses from a xpub, ypub and zpub according to standard derivation paths defined by BIP44, BIP49 and BIP84 respectively.
I checked with following example values (never use public data for any of your own coins!):
Example BIP39 recovery words, no optional mnemonic passphrase:
segment increase remain clown adjust home current regular noble scissors rigid mixture
BIP84 derivation for native Segwit addresses, Account Extended Public Key:
zpub6qNxGXAP2R4t764JVzCZmjCErqnePKwaqhxSNBYECwSaL25ufEDP3xmotADahCp7Fq82WtHJ1zFiBHqtURk4ALyEq3MiHSvHPWc8PbvNo34
First external address at derivation path
m/84'/0'/0'/0/0 is
bc1qv2d8c0wyu6mcnl0wyq9nx4ygpzty0r0e639jsl,
first internal or change address at
m/84'/0'/0'/1/0 is
bc1qse7q5jlnaj47hsl0trs6dwxec3z0z4pa4l49rk.
You can compare both and find them identical from
this bitcoinexplorer.org query (result after entering above zpub in top right search box of bitcoinexplorer.org).
I happens occasionally that bitcoinexplorer.org doesn't work properly, whatever problems they're facing. It's usually only temporarily (can only speak for me).
I would highly recommend, I do that myself, to use an own Electrum server to preserve your wallet's address privacy, but this needs some resources. E.g. with Umbrel you can easily have your own non-pruned Bitcoin Core or Knots node, Electrs or Fulcrum Electrum server and self-hosted mempool.space and bitcoinexplorer apps. Possible on a Raspberry Pi 4B with 8GiB RAM (recommended RAM size) or a mini pc for which I'd recommend at least 16GiB RAM to have enjoyable performance. Both setups will need at least 1.5TB storage, preferably a 2TB SSD (I don't really recommend spinning disks for such things, just painfully slow to sync).
(You could still squeeze Bitcoin Core node, electrs Electrum server into 1TB disk space but you won't have much space left, few dozen GiBs maybe; you will run out of space pretty soon and ruin invested time and bandwidth for the setup.)
If you don't like Umbrel, you could use anything else that provides a more or less easy setup for your own Bitcoin node, Electrum server and blockchain explorer apps. There are enough choices out there and the RaspiBolt project provides details for those who like to setup all themselves by getting your hands dirty with step-by-step instructions. Some experience on the Linux command-line is helpful for the latter, Umbrel is more for the mouse petters.
