Hello @MichaelHan-MSFT ,

You can use the following suggestions:

1.Reset the cache(index file)
Site settings >> Site collection object cache >> check the box for “Force this server to reset its disk based cache”
It will be regenerate cache(index file) when you accessing this page next time.

2.Install the latest version of security update for SharePoint Server 2019.
If clean the cache does not work, it is recommended that you install the latest version of security update for SharePoint Server 2019.

Microsoft Official Resource:
Description of the security update for SharePoint Server 2019: October 13, 2020


Here is a similar case for reference: Error occured with Blob Cache in

Thanks,

This is normal, actually. If I recall, it is related to the favicon not being available. The ULS logs should have more information on which file is unavailable.

Slow page load could be indicative of multiple issues, such as poor overall server performance, be it SharePoint or SQL (network, disk, CPU, memory). Or it could be poor page structure (i.e. adding a bunch of List webparts on a page that make expensive queries).

If you haven't, also take a look at https://docs.microsoft.com/sharepoint/administration/cache-settings-operations.
