Thanks for your post in Microsoft Community.
The information you have provided looks like Explorer has crashed, and in this case it does appear that the system is freezing.
Based on the reported error I can give you some options to try.
1, try "Win + R" > type "Control.exe"
2, top right corner click on view "large icon" > click on "Indexing Options" (Indexing Options)
3, click on "Indexing Options" > click on "Advanced"
- Click on "Rebuild" > After rebuilding, restart your computer.
If the above does not work, try right-clicking the Start button > select "Windows PowerShell (Admin)" (PowerShell administrator mode) > paste and run the following command
Get-AppXPackage -Name Microsoft.Windows.Cortana | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
If anything is unclear, please do not hesitate to let me know.
