Adobe in it's various troubleshooting pages, often sites out of date GPU drivers. Probably nothing to do with your keyword issue,

I see you have v382.05. At NVIDIA Driver site, current would be v460.09. Your way way behind.

You should have a NVIDIA utility called GeForce Experience. Use it to update the driver. When you do, select Custom install type as to force a clean install.

Have you considered resetting (aka restore) the preference file? This is not the same as returning all preference settings to default (although that may occur as a result of resetting) . Resetting the preference file is Adobe speak for deleting it, whereupon launching LrC a new one is created. The preference file can get corrupted leading to buggy behavior. A corrupt preference file will survive updates, upgrades, re-installs.

I tried both of your suggestions (resetting the preference file & upgrading the display driver); however neither of these changes fixed the issues. When I upgraded the display driver, I lost control of the display brightness with the buttons on my PC, so I went back to the original display driver. Also noticed additional problems doing a photo import - no import occurred until I rebooted the PC. Thank.s for your suggestions

I rolled back to Lightroom Classic Version 10.0. The PC freezing issues have completely resolved themselves. The keywording issue remains on an intermitent basis (mostly does not auto-complete previously entered keywords, but occasionaly does).
