Clicking the magnifying glass opens the search function but the window is completely blank. Nothing. No error message, no "couldn't find anything" message, no results whatsoever - just a blank box. This error comes after installing some new software. I tried uninstalling but with no luck.
For troubleshooting I ran sfc /scannow, which resulted in no errors found.
Also tried the DISM command.
Also tried stopping and restarting SearchUI.exe, Windows Search service.
Also tried rebuilding index.
