Just upgraded several software items in the "Creative Cloud!" Photoshop opened just like it always has. Lightroom v10 gives me this message: Unexpected error opening catalog. The catalog could not be opened due to an unexpected error.
I spent several hours online Sunday, since supposedly the help line phone is only open on Monday thru Wednesday. Lightroom still doesn't work!!!!
Today, on Monday, I called the "help" line. Some guy answered, and then immediately put me on hold. After listening to white sound for several minutes, I hung up and called back. This time after beind routed thru their pre-programmed selection process, I got a recording that said I would be on hold for an hour and forty minutes??????
I use Lightroom a lot to catalog my images, and have done so for a number of years. Ihaven't been able to work on any photograph now for three days.
I become more irritated with Adobe everytime I encounter their countless problems and the way they treat their loyal customers. May not be one much longer!!!!!
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.
