After editing a picture in Develop module the Library module picture (same picture) is much lighter.

After updating to the 13.0.1 I have noticed when I edit my photo in the Develop Module the outcome (showing in the Library Module and upon exporting) is MUCH lighter (exposure is too light). If I switch between the two modules there is a difference in the exposure of the photo.  If I export the photo, the outcome is the lighter version (the one that shows in the Library module).  VERY FRUSTRATING.  I had to go back and forth to determine the exposure for my photo's before posting the photos for the client. Never had that problem before.  I have my profile settings set to use the camera settings. Anyone know why this is happening?

What version of MacOS? What is set as monitor profile? What export settings do you use? I can't reproduce this on my Mac running MacOS Ventura and Lightroom Classic 13.0.1. The Develop module and the exported image are identical.

I am using Sonoma Ver. 14.0.  Where do I find my monitor profile?  I went in and set my Use Graphics Processor to off to see if that helps (per someone who has the same problem).  It doesn't have anything to do with exporting because this happens before I even export - happens during editing my photos.  I ended up having to make all my edits appear darker in the Develop module in order for the exposure in the Library module to be close to what I want the final image to look like.

I ended up turning off my Graphics Processor under Preferences and that seems to have done the trick.  Now both modules are the same as far as brightness (exposure) goes.  Don't know what other things that may affect though!!
