SharePoint 2019 Communication Site DENY editing permission

I have a SharePoint 2019 Farm (Single Server) that we are using to evaluate an upgrade from 2013. I set up a new communication site and customized the theme and installed a number of apps. Recently, I applied some server updates to the server, which included some SP2019 updates. Since the updates, any Communication site I create makes the "Home Page" not able to edit. There is actually a "DENY" permission on my user account. If I make another page the Home Page, I can go into the original page and edit it, but as soon as I set it to the Home Page again, it becomes locked.

I can not find any settings that would do this. Prior to the updates, I could edit the page from the home screen. As far as rendering, on the Home page, it does not even render the command bar and when I look at the code-behind using F12, there are two specific errors: 

Uncaught (in promise) TypeError: Cannot read property 'hasAllPermissions' of undefined
Uncaught (in promise) TypeError: Cannot read property '_currentElement' of null

This does not happen in the page if it isn't designated as the Home Page.

I have been searching the internet, but it appears that nobody has had this problem.
Any ideas?

    Hello @David Petersen ,

    Welcome to Q&A Forum!

    I can't reproduce your problem in SharePoint 2019.

    I installed the latest CU update package (August 2021) in my 19 environment, and I can edit home.aspx normally.

    We recommend that you perform the following troubleshooting:

    1.Check if the SharePoint update package of August 2021 is sucessfully instaiiled.

    2.Clear the browser cache and refresh the page or use another browser for testing

    3.View the Windows Event logs and SharePoint ULS logs to get detailed error reports.

    Thanks,
    Echo Du

    The update KB5002001 was missing. After the installation everything works again.
    It did not come with Windows Update, I had to download and install it manually. Thank you.

    This is exactly what was needed. I have been doing regular Windows Updates and I had one patch installed but the KB5002001 patch did not automatically install. I manually downloaded it and installed it and now I can edit the home page.

    Thank you for your help!
