Adjustment levels not working in Photoshop

[erikaj62844142]

Suddenly, I am unable to adjust levels on any file/image I'm working on. I have tried shutting down the computer and rebooting. I am able to slide the sliders but nothing impacts the levels of the image. The droppers don't work either. I wonder if I accidently hit some setting or there has been some update on I activate this feature overnight. If you have any advice, I'd appreciate it. Thanks.

Hi

What exact version of Photoshop do you have, 21.2 is the most recent version

Yes, I am using the CC 2020 version.

Hi, Same issue here. Level not working. Histogram blank. I'm running Photoshop on IPad Pro, latest version.

I'm having the same issue with the new (2022) version of Elements I just downloaded. The levels adjustment isn't working. Moving the slider has no effect on the image.

I'm using Windows 11
