For whatever reason when Lightroom last updated, it now drastically changes my Nikon raw files when they Import. I have never had this problem before. I would import my raw NEF file and the preview would look exactly like the view in my camera.  Now when I import the images are 2-3 stops too dark and I cannot figure out how to set lightroom to view the images as shot.  There has to be a way or LR becomes useless for time lapse.  I have 10,000 images from about 15 time lapses and use LRT time-lapse together with LR. LRT views the images properly.

Does anyone else have this issue and how can I get back the profile that fits my camera? Using Nikon D810 and D850's.  I check marked in preferences to use the profile based on my camera's serial number but that didn't do squat.

Right now LR is unusable. 

Appreciate any help you can provide.

Yes contact Adobe support on Adobe.com. I contacted them twice recently about Photoshop 2020. The first time with the first problem I talked to someone on the online chat. He was super helpful and logged into my machine remotely and reset some Photoshop preferences and that fixed the problem. The second time I contacted them about a different problem. I used chat support again and got someone clearly much less knowledgeable than the person I spoke to the first time, he gave me some dumb answer that made no sense and then told me to go to the Adobe forums. I instead just called up their support phone number and spoke to a different person who was quite a bit more knowledgable and willing to help and the problem got solved.

That solved it. Reset developer mode. Bingo.
