God bless you, dear friend. As soon as I have some merits, they are all will be yours. Very, very helpful. thanks a lot
Thanks a lot.
How can I integrate m / 84 '/ 0' / 0 '/ 0/0 into my code? I just need to get the first 5 addresses. I looked at your program, but there is a whole class forming a complex configuration. Too difficult for a beginner. How can I just hardcode the derivation path into my method?

Wrong derivation path for a child key. For bc1q0u... you need to use m/84'/0'/0'/0/0.
Take a look at my program https://github.com/PawelGorny/lostword, you may launch it with configuration:

Also you'll probably want to discard that seed that you used for testing above, now that it has been posted in the open and web crawlers have archived it.
