[Branched] I open lightroom classic and it becomes unresponsive

[crocdoc]

I'm having a similar issue with Lightroom classic. It's been working fine for years, but now when I open it is unresponsive and just hangs. I can't follow your recommendation for I am unable to access preferences. I've tried opening different catalogues, I've tried using different external hardrive sources for the images, I've uninstalled and reinstalled Lightroom. I am just unable to use it. It opens, then hangs. I use task manager to force quit, have restarted the computer numerous times, you name it.

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.

For a better help we also nedd more inforamtions about your system including the following:

• Adobe products and version number
• Operating system and version number
• Computer hardware, such as CPU; GPU; the amount of RAM; etc

Please post the exact version numbers and not only phrases like "recent" or "latest".

Try resetting the preferences of Lightroom Classic:  How to reset Lightroom Classic preferences (adobe.com)

In the linked document is also described how to reset the preferences in case LR doesn't start correctly (see section: Method 2).

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

BTW: You’ve reactivated an approx. two years old thread. And you wrote only "I am having a similar issue". It may seem like it's the same or a similiar problem, but it may not be. Also, you're not giving us any information about your system and what you've tried so far. I've branched your post into a new thread.
