Try to follow the tips suggested above, you can also "refresh" new addresses from your xpub/descriptor in Bitcoin Core with the keypoolrefill command in Bitcoin Core.
To understand how output descriptors work and an example of how to use them, you can access this topic: https://bitcointalksearch.org/topic/m.63603357
Optionally, to better suit your case, you can define a "range" variable in the descriptor to generate, for example, 5000 addresses, e.g.: ..."range:"[0,5000]... this must be added in the descriptor to be imported, for example:
