I'm wondering if this is related to https://answers.microsoft.com/en-us/windows/forum/all/cumulative-updates-for-windows-10-and-windows-11/6d7fccc6-e125-4ae4-9fbb-db7077065c31#:~:text=After%20installing%20this%20update%2C%20some%20.NET%20Framework%203.5%20apps%20might%20have%20issues%20or%20might%20fail%20to%20open.%20Affected%20apps%20are%20using%20certain%20optional%20components%20in%20.NET%20Framework%203.5%2C%20such%20as%20Windows%20Communication%20Foundation%20(WCF)%20and%20Windows%20Workflow%20(WWF)%20components. 

(I don't know for sure that this is the issue, but it may be worth trying the fix Install .NET Framework 3.5 on Windows 11, 10, 8.1, 8 - .NET Framework | Microsoft Docs - please let us know.)

Answer 2

>> .... it may be worth trying the fix Install .NET Framework 3.5 on Windows 11, 10, 8.1, 8 - .NET Framework | Microsoft Docs

You were correct!

The updates I installed yesterday included 2022-05 Cumulative Update for .NET Framework 3.5 and 4.8 for Windows 11 for x64 (KB5013628), which may have been part of the cause of the problem.

I followed the link to your suggested fix, and using the instructions there I went to Windows Features, where I saw that ".NET Framework 3.5 (includes .NET 2.0 and 3.0)" was not checkmarked.

I checked the box, waited for the download, waited for files to be applied, and restarted.

Success!

Thanks!
