Steps to reproduce

About a month ago, I installed MSER in Service Mode (after a long time). Shortly after that, I discovered that some Windows Apps and settings don't work (Windows Calculator, Microsoft Copilot, Xerox Print Experience - looks like not all of them, just some specific...). On top of that, some Windows settings buttons stop working. It took me a while to discover that if I shutdown or reinstall MSER in Active Mode, the problem goes away.

Logs

AppFailures.log, AppSecurity.log, PEBIAT.log and URIFailures.log are completely empty (untouched since first install). AppGeneral.log shows only a valid Windows Search box redirects which were completed successfully.

✔️ Expected Behavior

MSER won't interact with UWP apps startup.

❌ Actual Behavior

MSER in Service Mode prevents some (including but not limited to those listed) apps from starting. This applies also to the case when I find that app's EXE directly and execute it that way. It just doesn't do anything.

Microsoft Windows version

23H2 Build 22631.4112

Other Software

Windows Calculator 11.2405.2.0 Microsoft Copilot 1.0.4.0 Xerox Print and Scan Experience 9.21.12.0

List is probably incomplete, just to name a few...

I will keep this open and close https://github.com/rcmaehl/MSEdgeRedirect/issues/428 since it only mentions Calculator.
