Lightroom Classic won't launch

[hughes_nz]

I can't get Lightroom Classic to launch. When I try to I get spinning wheel while the computer thinks about it for a second then nothing happens, but Lightroom Classic shows up as a Background Process in Task Manager. This only happens with Lightroom Classic, I also have Photoshop and Lightroom (not classic) and both of those work with no issue. I have tried un-installing + reinstalling including using Adobe Creative Cloud Cleaner but always with the same result (everything except Lightroom Classic works). Is anyone able to help or experienced something similar? Details below.

Creative Cloud 5.3.1.470

Lightroom Classic 10.0

Windows 10 Pro Version 20H2

This just happened to me. It seems to happen for different reasons for everyone.

I just waited for the next app update, and it was right as rain. But this wasn't before I had uninstalled, reinstalled, moved folders...

@hughes_nz , That is very same diagnosis that i have too, everything else works like Adobe Lightroom CC & Adobe Photoshop but just not Adobe Lightroom Classic.

But my Question to @Todd Shaner is how do i "Save your work" on Lightroom Classic, if cant even open your Lightroom Classic to do so, plus i have nothing i want to save all my images are exported from Lightroom Classic, i am Frustratedly waiting to get onto Lightroom Classic (which i pay £9.80 for) to edit some RAW Files of White Throathed Dippers, that i am Very Excited to see what i have Created, but i cant!!

Hi all,

For me it turned out to be a bad catalouge file that the program was trying to open on with default. I found my folder with all my other catalouge files and then was able to open Lightroom Classic by clicking on those catalouge file links.

Todd, your answer seems to be incomplete. "then hold down the ALT and SHIFT keys and click on the LrC shortcut."

Hold down the keys where? What am I supposed to select? What is the LrC shortcut? Where am I supposed to find this? I am on a 2023 machine with a web based LR

On your keyboard, use one finger to press down the ALT key, use another to press down on the SHIFT key, (do not let go) and use your mouse to click (double click?) on then icon on your desktop, or down in your taskbar, that is the LrC shortcut. (then release those buttons).
