There is a weird and really rare bug inside of the coinbase wallet application which derived the one single address wrong only that one time.
While this definitely is not impossible, it is rather rare.

Running with this idea, it is at least theoretically possible since Coinbase so easily switches between Legacy and Segwit addresses, that it has derived a Segwit address from a Legacy derivation path. You could try using Ian Coleman's site (offline, of course), enter the seed phrase, scroll down to "Derivation Path" and click on "BIP141", enter m/44'/0'/0'/0 in the box titled "BIP32 Derivation Path", and select "P2WPKH" in the drop down menu titled "Script Semantics". This will generate Segwit addresses at the standard Legacy derivation path.

It would also be worth checking change addresses of that account using m/44'/0'/0'/1, and checking further accounts using m/44'/0'/1'/0 and m/44'/0'/2'/0, and checking the change addresses of those accounts too.

Just tried, the address with the money does not appear in the list.
When you say to check the change addresses, have I already searched them by inserting those settings you just told me or do I have to do something else in order to check them?
I tried all the combinations you've listed and the address did not appear in the list.
