I have never been able to use Lightroom CC Desktop version. I updated to version 1.5 a few days ago. My problem still remains. I had similar problem with Lightroom Classic CC and Photoshop CC. That problem was solved by disabling GPU (AMD). This, however has not helped for Lightroom CC. Lightroom CC does not open, so there is no way to adjust preferences. I have included screenshot below. I have been sending crash reports to Adobe, no use. This is highly frustrating, to say the least!

Hi Vijay, if disabling Use Graphics Processor fixes the problem, it's likely a driver issue. Have you tried updating your driver by going directly to the AMD or nVidia website to download and install the latest driver?

My current problem is with Lightroom CC Desktop. It does not start at all. Disabling GPU helped for Photoshop CC and Lightroom Classic CC. Not for the cloud version (Lightroom CC Desktop). I have tried updating AMD Driver etc. It does not help.

Ok. Vijay, 

We will need to make a manual edit to your preference file to kill the GPU.

The preference file is located here: C:\Users\[user name]\AppData\Roaming\Adobe\Lightroom\Preferences\Lightroom CC Preferences.agprefs

This is folder hidden in Windows by default.  You may need to set your Windows environment to reveal this folder. 

Open the file above in Notepad and locate this line:

useAutobahn = true,

set it to

useAutobahn = false,

Save the file

Launch Lightroom CC.

Let me know how it goes!

I don't have the file in that path.
I am attaching a screenshot of the folder. There are files related to "Lightroom 6" and "Lightroom Classic CC 7", but not "Lightroom CC".

Correction: C:\Users\[user name]\AppData\Roaming\Adobe\Lightroom CC\Preferences\Lightroom CC Preferences.agprefs

I did a typo on the first pass

That folder is empty, I am attaching the screenshot

But, I think we are on the right track now. We must find out why the preference file does not get installed. Is there a way to get the default file downloaded?

Interesting... 

Will it allow you to start with a reset preference file: 


1. Hold down [Alt/Opt]+[Shift] while launching Lightroom. 
2. Overwrite the Preferences when prompted by the dialog.
3. Close Lightroom.
4. Restart Lightroom.

Sorry, that did not worked either. With Alt+Shift depressed, I restarted Lightroom. Got the dialog for resetting preferences to default, chose Yes for default preferences, Lightroom CC crashed as earlier, no change.

Then I tried something else.
1. Installed Lightroom CC on another computer.
2. Got it working,
3. Copied the "Lightroom CC Preferences.agprefs" to my computer
4. Restarted Lightroom CC. It crashed again.
5. The preference file was still there in the folder.
6. I then restarted with Alt+Shift depressed,
7. Said yes to reset preferences to default, Lightroom CC Crashed again.
8. This time, when I looked for preference file, it was missing.
     Curiouser and Curioser!!!
