You may want to uninstall and reinstall Lightroom Classic. Sometimes OS upgrades in place do not work as intended.
  • Close Lightroom
  • Restart the computer
  • Use the Adobe Creative Cloud App to uninstall Lightroom Classic
  • Restart the computer
  • Install Lightroom Classic via the Creative Cloud App without launching any other programs.
  • Restart the computer
  • Launch Lightroom
  • Wait 5 minutes
