LrC don't start after update to v 11.0.1. What shall I do?

I've moved this from the Using the Community forum (which is the forum for issues using the forums) to the LrC forum so that proper help can be offered.

The first thing that you should try is to switch off the GPU support from the Lightroom preferences and check if that helps to fix the issue.  If Lightroom doesn't start correctly the please see "Solution 2" in the linked document. 

Troubleshoot GPU issues | Lightroom Classic (adobe.com) 

  

Another step is to try to reset the Lightroom preferences. Hold down Alt and Shift (Windows) / Opt and Shift (Mac) while you're opening Lightroom and it’ll ask whether to reset the preferences. Click on "Reset Preferences".

If this doesn't help we need more informations about your environment. 

Which operating system do you use? 

Which version of Lightroom do you use? 

Please post the exact version and not only phrases as "recent", "latest" and so on. 

  

Do you get an error message? If yes, please post the exact message or an screenshot.

This I've wrote in my answer earlier.

Did you check for a lock file?

Vad är det och hur hittar jag det?

Please take a look here: The Lightroom catalog cannot be opened because another application already has it opened - lrcat.loc...
