New problem MS store seems broken, but I did fix the Lync problem myself, so no more red warning messages.
The MS Store has been quite the disaster for me. I HAVE to use it for Xbox Gamepass but last time it tried to update Microsoft Flight Simulator it gave a useless error. I tried uninstalling and now it wont install at all.
What makes this worse is the DRM and permissions crap that Microsoft use makes a real mess of storage. Somehow it makes it so you can't manually remove anything Windows put into WindowsApps, even Linux can't do it. So I have left over files from when it broke last time and I renamed the folder (somehow it let me do that) that I cannot remove without a complete format.
I also had the issue where Metro Exodus crashed after the intro movie, on all other stores you fix it by removing the movie files but of course the Windows Store version is locked away so I just couldn't play it at all any more.
