Windows 10: Has something changed on allowing ISSetup.dll unsigned in smart app control?

We have an application that uses an older license of Flexera InstallShield 2015. It doesn't sign a dll at install time that is now being blocked by smart app control. We have a build from two months ago that allows this DLL on a recent device, and our build as of yesterday, no longer works.New load, last few days: Code Integrity determined that a process \Device\HarddiskVolume3\Users\examt\Downloads\Examplify-3.7.0-6716524_win.exe attempted to load \Device\HarddiskVolume3\Users\examt\AppData\Local\Temp\{79168F0C-D9A9-4BE1-841E-257A44552D94}\ISSetup.dll that did not meet the Enterprise si

Smart App Control





So I used Visual Studio to create simple Windows apps that will automate my work, and most of these consist of less than 1,000 lines of code.

I also made an app for my cousin that makes it easier for them to design menus and social media posters for their bakeshop, with few clicks. My apps were blocked right away by Windows 10's Smart Screen, but that's something that you can work your way around with.

But with Windows 11's implementation of Smart App Control, the only way to run my apps is by signing them.

And should I be worried about my apps getting blocked by Smart App Control? Does it block all unsigned apps?
Will it block programs that I debug in VS?
If yes, how can I use my own apps on my work computer running Windows 11?
I think Smart App Control is beneficial to those who don't know what they are doing on Windows; but for technical users; it will only get in our way.
For users who open, download, and double-click any malicious, executable attachment disguised as a Word document, Smart App Control is for them.
