Error in startup of Lightroom "failed to open a model (...) Cannot find parent lua model"

[defaultctehxwb6p73b]

Hi,

since  couple of months I have an error while starting the cloud-based Lightroom. As I'm usually only using Lightroom Classic, I didn't care about the problem. But I'd like to use now the Clod-based Lightroom. Please find below the screenshots of the error messages and the system information.

After the startup Lightroom looks completely crippled, all menus only have place holders for menu texts. I already reinstalled it and deleted the two folders

C:\Users\...\AppData\Roaming\Adobe\Lightroom CC

C:\Users\...\AppData\Local\Adobe\Lightroom CC\Data

Still nothing changes. Any ideas are appreciated.

Thanks!

My first recommendation would be to perform a clean reinstall.

Clean Lightroom Install Procedure

1. Close Lightroom
2. Restart the computer
3. Use the Adobe Creative Cloud App to uninstall Lightroom
4. Restart the computer
5. Install Lightroom via the Creative Cloud App without launching any other programs.
6. Restart the computer
7. Launch Lightroom
8. Wait 5 minutes
   
   If that does not cure the error messages, I would then reset the preferences.
   
   This procedure works for both Lightroom Classic and Lightroom Desktop. If you are using Lightroom Desktop, it can change your local storage location. Please review this setting after resetting preferences. 

Reset Procedure:

1. Close Lightroom.

2. Hold down [Alt/Opt]+[Shift] while restarting Lightroom.

3. Overwrite the Preferences when prompted by the dialog.

4. Close Lightroom.

5. Restart Lightroom.

When opening Lightroom (Windows) I get this error. I've tried uninstalling the app and downloading different versions - older and newer. Please help.
