This is a Microsoft issue and nothing on our side we can fix easily as this would mean to change the code of a vast amount of older trainers.
Please let Microsoft know.
But my little finger tells me that if Microsoft happens to implement this change to all windows 10 users in the future, CH will have to change their older authentification method anyway (fair or not). I doubt Microsoft give a rat's derriere about workability of what is probably considered like malware/unsafe software to their eyes.

Create the feedback in the Feedback Hub and link it here anyway so that other Insiders can up vote it.
Search for it and up-vote it, I submitted a screen shot and let them capture data for the issue. I'm not sure how else to "link" it here with a URL, I don't see an option like that but let me know if theres anything else I can do with that feedback.
Hopefully PW got some good info on what's happening from probing my system and can figure an easy way around it without having to mass-recode the older trainers (something inbuilt to the Trainer Manager perhaps?)
Here is a link to it: Link
*My first CH post! yay~*
This is not entirely true. We faced a similar issue with the Windows 10 Anniversary update where the new Windows Defender was blocking a large number of our trainers for no reason and without notifying the end user. After many users submitted reports to Microsoft along with us reaching out to them, they fixed the issue. Our trainer authentication is a simple API call that has existed since Windows 95. If their latest build broke our authentication then it likely broke many other applications that use the same API calls. So, I recommend that anyone with this issue please do report it to Microsoft.
