When the last update hit, the Client.CBS package (which provides the new screenshot overlay/feature) on my system got de-registered for some reason, I think I solved it with this in powershell, as admin: Code: Add-AppxPackage -register "C:\Windows\SystemApps\MicrosoftWindows.Client.CBS_cw5n1h2txyewy\AppxManifest.xml" -DisableDevelopmentMode + a reboot The SystemApps folder might not be accessible by default, you might have to take it over from trustedinstaller, I can't remember.
Makes sense, textinputhost.exe is part of that package. Try killing your window customizer and all instances of explorer.exe
I configured that on this, instead of pressing 3 buttons simultaneously, just one PrintScreen button & have no issue in this. Why don't you try this?
I know realy but I've been on the road with M$ from my 14th life year and I'm now almost 50 @Enthousiast and tbh I do'nt let it get to me any more so
