P: Message: "The catalog could not be opened due to an unexpected error."

Hi, I have been lucky enough to be able to test the 10.3 version for some time now to see if it fixes the issue and it did for me. So hopefully with the release ( I was actually able to update to 10.3 today) this problem might be fixed for many people! Fingers crossed! 

Has anyone tested the June 2021 update, LrC 10.3?

If so, does LrC 10.3 fix the issue with "The catalog could not be opened due to an unexpected error" ?

I realize that this is an intermittent issue for many folks, and we won't know for a week or more if it really is fixed.

Same Problem here. Suddendly from one day to the other, LR stopped working between closing and opening it, even with backup catalogs. Also get the "Unexpected Error" messages and can't use the program anymore.

I am also having this same problem - tried all recommendations in this thread and nothing helped!  

Having the issue with 10.2, but it returns normal after I rolling back to 10.1.1. I remember there was the same issue when I update to 10.1, adobe you're really bad at making updates, aren't you?

I did the procedure but
I cannot find the logs that should be generated in the Documents / LrClassicLogs folder
LrClassicLogs is nowhere on my imac

I went back to version 10.1.1

Just an update from me, the thread starter. (May 19)

For unknown reasons, LrC 10.2 has been behaving quite normally for me for the last couple of weeks.

I have not been doing anything out of the ordinary, except just using and testing LrC daily.

How did you save your presets if you had any if you weren't able to open the program? I would also go back to an older version but want to make sure I don't loose anything since you have to uninstall and reinstall. 

Good short term solution! But I guess there needs to be a longterm fix 😞
