Lightroom Classic V11.4 installed automatically on my Laptop last week. It opened up ok the 1st time I used it. But today, it will not launch at all. Tried restarting PC several times to no avail.

When viewing my catalog data in my PC folders I see some files (including latest Catalog data file) flashing on and off after an Ircat.lock file. is this relevant?

Do you actually get an error message when Lightroom Classic refuses to launch? If so, please provide the complete exact unedited word-for-word error message.

Hi dj-

I get no error message at all. I click on LrC tile on desktop and just see a spinning wheel for about 2 seconds and that is it. I also try launching from Adobe Cloud panel and from my programmes menu. All with the same result.

LRC appears to open in the background using up processing power, showing on my tasks list, and adding those flashing files in my LR folder, but I just dont see any of it on my monitor.

Have you tried opening a different catalog file?

Please try to deactivate the GPU manually. See "Solution 2" in the document behind the second link.

Troubleshoot GPU issues | Lightroom Classic (adobe.com)

Another step is to try to reset the Lightroom preferences.

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

Do you get an error message?

What has been change on you system before the error occur?

Lrc updated to V11.4.1 today. But still not launching. Tried disabeling each of my 2 GPUs in turn with no avail.

I deleted the Lrcat.lock file in my folders. but I still get two other files flashing up. These are:

Lrcat-shm

Lrcat-wal

They flash on and off continually. do I need to delete these too?

Extra info: Just noticed this: My Laptop Fan has been running continuously since I tried to launch LRC.

I stopped task and within 2 minutes my fan stopped. It appears that Lightroom was running as a background task making laptop run hot. I will try and re-launch and see what happens.
