Bitcoin core: 0/unconfirmed, not in memory pool

I have been trying to create a transaction using bitcoin core during the last 6 hours but it always shows “0/unconfirmed, not in memory pool” in the transaction details, even waiting for more than 2 hours. The node is fully synced (it has the check mark in the bottom right of the UI). I created a new transaction using 0.00040000 BTC per kilobyte as tip which is more than the displayed values in https://mempool.space/, but it didn’t work.

This is the transaction info in the UI:

And here it’s the information from listtransactions:
