When I close Lightroom Classic on my Windows PC, it doesn't appear to close completely. If I try to relaunch the program, I get an error message saying there's already a version running, and that I would have to try to open using a different catalog.  I have to reboot my machine to be able to launch Lightroom again.

Any ideas?

Have you quit using Task Manager? Try that and restart your system to see if that clears up the issue.

Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Paste that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut as that is just so much dead space to us non-Techs.
