Lightroom not does not open

Question

I have run lightroom on my windows 10 for many years without a problem. Suddenly it takes ages before opening and when I try to open a catalog, it subsequently freezes and it indicates that Lightroom does not answer.

I have tried unistalling and reinstalling but to no avail.

Also I tried to reset the preferences to the default settings but the app. does not respond.

Finally, I tried to create a new catalog by holding the Ctrl-Key while starting the app. The app indicates that it will prepare a backup, starts the backup and the it freezes again: the app does not answer.

Thank you for your help.

Unfortunately you haven't given us any information about your system. Therefore, all proposed solutions are a look into the crystal ball

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.

We need more informations about your system.

What version of Windows do you use?

What version of Adobe applications are installed?

Which hardware do you use?

What has been changed on your system before the error occur?

Try is to switch off the GPU support from the Lightroom preferences and check if that helps to fix the issue. Go to Lightroom > Preferences > Performance tab > Uncheck "Use Graphics Processor" > Restart Lightroom.

You wrote you have done a reinstallation of LR. Do you do a clean installation?
