Lightroom Classic very flaky.

Windows 11

It's reporting the following error, intermittently when synching metadate over multiple images.  This can sometimes be fixed by closing/opening LRC, sometimes, not so much

~~~~~~Arggh, I couldn't replicate, but the error was to the effect that the database or catalog failed ~~~~~  

Rebooting the computer was the only working solution.

It's also Refusing to accept my titles and descriptions.  When I enter them and move to the next file, if I return to the one just edited, there is no title nor description.  If I type the first letter of the title previously entered, the suggestion of the entire title appears.  After closing and reopening several times, the title and description finally appear.  This is not a lightning fast computer, but it's no slowpoke, either.

Also, when two images are stacked and one of them is labeled red, it cannot be unlabeled withoug unstacking
