Hi @IBN
Most probably the app registry might be corrupted and you can try these steps and check after each step if the app works.
-Try to reset the app
Windows Key+i > Apps > Scroll down to this App > Click this App > Advanced options > Reset
-Reset Microsoft Store through Command Prompt
Type cmd in Windows Search box > Right click on Command Prompt > Run As Administrator > Type WSreset.exe and click Enter > Reboot your computer
-Re-register All Store apps (You will get many Reds, ignore them)
Windows Key+X > Windows Powershell (Admin) > Copy the below code and restart once it is executed
Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
Hope this resolves your Query!!
