Hi, 

Since updating my LightroomClassic from 9.2 to 9.2.1, I can no longer open it. My computer comes up with an error message saying:

"The Lightroom catalog named "Lightroom Catalog" cannot be opened because another application already has it opened. Quit the other copy of Lightroom before trying to launch".

I only have one Lightroom open and clicked it like normal. I have tried several times, making sure I don't have anything related to Lightroom open on my computer.

Please could someone help! I use Lightroom for my work and can't work without it, so speedy advice is very welcome!

Thank you in advance

There is a .lock file in the same folder as your catalog. Goto this folder in Explorer/Finder and delete this file.
