I was trying to adjust the exposure on an image (same way I've done it for 2 years) and each time I slide the expose bar (in develop mode) it automatically slides all the way over to black all by itself. I've rebooted and it is still happening.
Is this happening to anyone else?
Would suggest you to reset Lightroom Preferences and then, check.
Refer this article for instructions : Resetting (or 'Trashing') the Lightroom Preferences file - Lightroom Forums
If that does not help, share below details :
