Lightroom classic 14.2 does not launch at all. Removed it, reinstalled it still not. Lightroom classic is essential to my work. How to fix this???

Something like this happened to me recently. Very similar symptoms. It turned out that I was trying to load a corrupted catalog. The catalog had been corrupted by bad RAM in the new build I had just finished. I unzipped the most recent backup, renamed the bad catalog, the copied the unzipped backup to the Lightroom Classic folder and it started right up.

Do you get an error message? If yes, please post the message word-by-word.
On a first step you should restore the LR preferences to the default settings.
Goto to the following folders:
- macOS: com.adobe.LightroomClassicCC7.plist
- Windows: Lightroom Classic CC 7 Preferences.agprefs
Restart your computer and launch Lightroom Classic.
If this doesn't work try is to switch off the GPU support.
Navigate to one of the following folder:
- macOS: /Users/[username]/Library/Preferences/com.adobe.LightroomClassicCC7.plist
- Windows: C:\Users\[user name]\AppData\Roaming\Adobe\Lightroom\Preferences\Lightroom Classic CC 7 Preferences.agprefs
Open the one of the following files in a text editor
- macOS: com.adobe.LightroomClassicCC7.plist
- Windows: Lightroom Classic CC 7 Preferences.agprefs
Change (od add) the line useAutoBahn = true to useAutoBahn = false.
Save and close the appropriate file
Restart your computer and launch Lightroom Classic.
Please note:
(Windows) Some of the folders you're looking for could be hidden. To view them, choose Start > Control Panel > Appearance and Personalization > Folder Options. In the Advanced area of the View tab, make sure that Show Hidden Files and Folders is selected, and then click OK.
(macOS) The user Library file is hidden by default on Mac OS X 10.7 and later. For temporary access to the user Library file, press Option and choose Go > Library in the Finder.
Is your system up-to-date? Do you have installed all recent updates and patches for the operating system and the device drivers, especially the graphic driver. If you have a NVidia graphic card installed, make sure that you are using the recent Studio version of the driver, not the Game Ready version.

There is no error message. I just want to open LC and it does not launch,
scrolls a bit and happena nothing. But when I want to remove the program I
receive a message, that I should close the program before I can remove it.
The system thinks its open but its not.

Hi, I tried some, the program was removed and re-installed (several times so far, even tried older versions), everything is default, no preferences, no Nvidia graphic card, but I have problem with the latest update of W11, system message says, not enough partition space, which is BS, already enlarged the space and still does not work. I think it has to do something with that... However, its strange that everything else, PS, LR, AI runs except LRC which I need the most... 😞

It shouldn't, but I'm not sure.
How much free disk space do you have? Please show us a screenshot from the overview screen of the Disk Management tool in Windows.
Check the Windows event viewer if the appropriate entries for Lightroom Classic which allows conclusions to be drawn about the problem

Before you'll invest a lot of time I would recommended a complete and clean reinstallation.
Please follow the steps below:
- Backup all personal data, like templates, presets etc.
- Uninstall everything cc including preferences, https://helpx.adobe.com/creative-cloud/help/uninstall-remove-app.html
- Then uninstall the cc desktop app, https://helpx.adobe.com/creative-cloud/help/uninstall-creative-cloud-desktop-app.html
- Clean your computer of cc files per http://www.adobe.com/support/contact/cscleanertool.html
- Restart your computer (don't skip this)
- Reinstall the cc desktop app, https://www.adobe.com/creativecloud/desktop-app.html
- Use the desktop app to install your cc programs/trials
- Restore your personal data.
If you're unable to install the cc desktop app at this stage, use an administrator account (solution 4 here, https://helpx.adobe.com/creative-cloud/kb/creative-cloud-missing-damaged.html)
If this also doesn't help the next step shold be a complete and clean reinstallation of the whole system which all recent updates and patches of the operating system and driver for chipset and devices.

Plenty of free space over 800gb and added a lot space for W11 update, but it still did not go through... I will reinstall the whole CC...

One point you may check before you try a reinstallation.
Perhaps your previews or your catalog has a fault.
To delete the preview cache goto the folder that contains your Lightroom catalog in Finder. The default location is in the Pictures/Lightroom folder under your user folder. Search the [Catalog-name] Previews.lrdata file and drag it to the trash. Then restart Lightroom.
Try to hold the Ctrl-Key while starting LrC. This should opens a catalog selection dialog.
First select the appropriate recent catalog and let it check it – note the checkmark "Test integrity of this catalog" to check its integrity. If that doesn't help, try to create a new one and see if this catalog works. If yes, you could then try to import your current catalog into the new one.

Nothing works, I start to open LRC, nothing happens, no catalog dialog, no program interface. I see it runs behind, but cant see the program, I can only close in the file manager window.
