Lightroom Classic Won't Open

[default0actjiwwmvlv]

Help Please.  I can't get Lightroom Classic to open.  It worked fine for me last week.  Suddenly stopped launching.  I have tried uninstalling and reinstalling.  I have logged in and out of Creative Cloud.  I have rebooted the computer.  I have updated all my computer drivers, then gone through the cycle again.  It doesn't matter if I try to launch it from my desktop shortcut, the start menu, or within Creative Cloud. I get the little blue circle that spins for a few seconds...then nothing.  I have tried to go back and open from a backup catalogue.  Same thing happens.  I've searched through the postings and tried a couple other random fixes I found in here.  Nothing is working for me.  Getting desperate for a resolution.  

I am operating on Windows 11 Pro, and have the most updated Lightroom version through subscription service.

It seems that your preferences file is corrupt. This wasn't deleted by uninstalling Lightroom.

Please try resetting the preferences of Lightroom Classic:   https://helpx.adobe.com/lightroom-classic/help/setting-preferences-lightroom.html

Thank you for your respose Axel.  This didn't work either.  I actually came across this in my other searches through the forum.  Just to be sure, I have tried it one more time.  And it again did nothing.

Thank you for your response.  I did come across this advice in my searches through the forum previously.  I don't recall if I did this already, or if I never had it in the first place.  But I don't have a .lrcat.lock file that I can locate.
