I cannot open my Lightroom Classic-it is updated & my plan is paid up to date.

​@MsEfbomb ​@windrush123 Unfortunately you haven't given us any information about your system. Therefore, all proposed solutions are a look into the crystal ball.

Which version of Lightroom do you use?

Which operating system do you use?

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

Do you have restart (cold boot) your system?

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. In case of you’ve buildin a NVidia graphic card make also sure that you have installed the Studio version and not the Game Ready version of your NVidia driver.

First try to reset the preferences:  How to reset Lightroom Classic preferences (adobe.com)

It's recommended to backup your preferences before you reset the preferences to the default settings: https://helpx.adobe.com/lightroom-classic/kb/preference-file-and-other-file-locations.html
