nlocktime bug in Bitcoin Core v23 #25226

Recreating the bug report #25225 because the previous one closed by a party who doesn't know nothing about Bitcoin apparently.

Block height for nlocktime doesn't work and this poses a serious risk for smart contracts.

I have added block height to nlocktime and got converted to timestamp which corresponds to 1970/04/20 21:25:25

Found this bug when verifying a raw transaction.

What are the exact steps to reproduce?

Closing due to lack of details. You will need to provide exact steps to reproduce. Otherwise it is impossible for us to do anything. It isn't even clear whether you are filing this against the wallet, the mempool, the RPC or something else.
