LRC create a collection won’t work

[diannarucker]

I can no longer create a collection in Lightroom classic. It is updated to the current version. I click the + sign like I use to do but nothing happens. Help

Do you get an error message?

Please try resetting the preferences of Lightroom Classic:   https://helpx.adobe.com/lightroom-classic/help/setting-preferences-lightroom.html

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