Appears in Task Manager but doesn't launch

[Pietro Branchi]

I haven't been able to open LrC for two days.
When I click the LrC icon, there is nothing of its execution on the screen , but if I check the "activity manager" I find the LR Classic program is running
I tried to run Lr and it works normally, like Ps or Pr.

My version of LrC is 11.4.1.1 on 06/24/22
The operating system is Win 10 Home, version 21H1 Build 19043.1889
The free area on Disk C where the program is allocated is 42 GB.

Thanks for giving me a solution

I occassionally have this issue with a number of programs. I find that if I reboot, the problem clears itself. Here's a link to some other guidance https://helpx.adobe.com/ca/lightroom-classic/kb/lightroom-basic-troubleshooting-fix-most-issues.html

Thanks a lot for your reply, but I have not only rebooted but also uninstalled the app and then reinstalled.
