Hi @Mayank Bhargava ,
After my testing and searching(my sharepoint 2019 version is 16.0.10337.12109), I couldn't reproduce your problem, have you added code to this page?
You can try the following first to see if that resolves the issue:
- Whether all SharePoint pages have the same problem? You could create a new SharePoint page add Quick Link webpart to check.
- Check if the same issue occurs with other SharePoint sites 、 site collections and web applications.
If that does not help, please check the ULS logs and the Windows event viewer for more detailed error message.
