Hi @Addison Jiang ,
As per my test, I didn't reproduce this issue on my SharePoint Server 2019 which has installed the latest CU KB 5002329. To troubleshoot this issue, could you please verify the scope of this issue? If you go to another library in this site or go to another site collection under the same web application or go to a site under another web application, would the issue still persist?

@Addison Jiang ，
After discussion with my team, we suggest you can open a ticket to Microsoft. It seems to be a CU related issue and from our users end, we cannot fix it. Microsoft experts will give you instant help.
