**Expected behavior**
It is expected that Bitcoin Core is not shutdown automatically during startup. Moreover, it should be possible to set transaction fee at 0.

**Actual behavior**
![Bitcoin Core Error mintxfee](https://user-images.githubusercontent.com/111286121/210274894-e91adf7f-43f7-4c3f-b799-222c00dc34a0.png)

**To reproduce**

1) Click bitcoin-qt.exe.

**System information**

1) A wallet that contained unspent funds was opened previously.
2) The bitcoin.conf file contains "mintxfee=0".
3) Bitcoin Core 24.0.1 official binary for Windows (portable).
stdunique_ptr<WalletDatabase> new_db = MakeDatabase(db_dir, opts, db_status, error);
    assert(new_db); // This is to prevent doing anything further with this . The original file was deleted, but a backup exists.
    m_databreset();
    m_database = stdmove(new_db);
    // Write existing records into the new DB
    batch = m_database->MakeBatch();
    bool began = batch->TxnBegin();
    assert(began); // This is a critical error, the new db could not be written to. The original db exists as a backup, but we should not continue execution.
    for (const auto& [key, value]  records) {
        CDataStream ss_key(key, SER_DISK, CLIENT_VERSION);
        CDataStream ss_value(value, SER_DISK, CLIENT_VERSION);
        if (!batch->Write(ss_key, ss_value)) {
            batch->TxnAbort();
            m_database->Close();
            fsremove(m_database->Filename());
            assert( // This is a critical error, the new db could not be written to. The original db exists as a backup, but we should not continue execution.
        }
    }
    bool committed = batch->TxnCommit();
    assert(committed); // This is a critical error, the new db could not be written to. The original db exists as a backup, but we should not continue execution.
    return true;
