Kaspersky and Windows Preview build

You are using a development build of Windows 10, Kaspersky is not the only AV or app it will break. The code is going under major refactoring write now, so it will break old apps.

This is true of even older versions of Windows, the only difference is programs like the Windows 10 Insider Preview were behind the scenes and limited to a small group of beta testers. These days, persons are running preview builds in production environments which is the wrong approach.

Kaspersky developers right now might be experiencing the same issue as you do and are working on fixing it, but they are not going to do so far every Insider Build of Windows 10 because of the rapid release of updated builds which will be more significant with Redstone.

You likely won't see a fully supported version of Kaspersky until Redstone reaches general availability, which is in the second half of this year. That's if you don't like it, its best you stick with a fully supported stable build such as the Windows 10 November Update.

I find this ridiculous that Microsoft chose to force update customers through a very sneaky and shady practice.  Now Kaspersky won't work and I just paid for another year to autorenew.  So what I am hearing is that I can't use it, unless I BUY a commercial version of Windows 10?  Is this correct?
