As of today, I can no longer open Chrome Apps from the Windows 10 Startmenu. This worked up until yesterday evening's shutdown of the computer.
I already tried restarting the machine. Also, the apps still work, I can open them just fine from Chrome directly (in a separate window as intended).
All other apps in the windows startmenu, eg Chrome itself, Games, Lightroom/Photoshop, also still work just fine to start from there.
I was wondering what could have caused this. I didn't really notice any significant updates to Chrome or Windows yesterday.
