Now finally it works. I note what I did below.

 

I uninstalled Lightroom, and then reinstalled.

During installation, I got "Please connect to internet and try again" error when trying to activate the key (although my Internet connection is fine).

Therefore, I choose to install Lightroom without the serial key ( 7 day trials option ).

Somehow I can login into Lightroom with my adobe account, and I can normally use it now.

 

Thank you very much everyone for the suggestion and idea.

Try is to reset the preferences to the default settings by following the steps below.

  • Close Lightroom.
  • Windows: Hold down [Alt]+[Shift] while restarting Lightroom.
    Mac: Hold down [Opt]+[Shift] while restarting Lightroom.
  • Overwrite the Preferences when prompted by the dialog.
  • Close Lightroom.
  • Restart Lightroom.

 

It's recommended to backup your preferences before you reset the preferences to the default settings:

If this doesn't help try is to switch off the GPU support from the Lightroom preferences and check if that helps to fix the issue: https://helpx.adobe.com/lightroom-classic/kb/troubleshoot-gpu.html

If Lightroom doesn't start correctly the please see "Solution 2" in the document behind the link below.

Troubleshoot GPU issues | Lightroom Classic (adobe.com)

 

Another try is to check if there's a .lock file in the folder where the catalog (.lrcat) file resides. If there is a file with the .lock extension delete this file and then try and restart Lightroom.

The Lightroom catalog cannot be opened because another application already has it opened - lrcat.loc...

I tried reset preference, and I got this screen instead.

I also tried remove the .lock file.

So far, I still stuck at the screen like in the screenshot above.
