After not having used windows much for a few months, and after the most recent update, the function to launch apps using Explorer keeps stopping working. I can't launch any apps from the taskbar or from the Start menu. Forcing a restart of Explorer in task manager gets it working again, but only for a short time. Rebooting obviously works too, as far as getting launching apps working again, but, like forcing a restart of Explorer, it is only a short term fix. 30 minutes later, when I want to launch another app, it doesn't work. How can I fix this? I'm using 21H1.
