**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).
