P: Lightroom Classic: Editing raw file in PS from LR loses profile

er no... i use Nikon D850 and D600. It happens to NEF file too. I think it's the ACR in Photoshop has problem with custom camera profile, not the raw file type.

I use the RNI presets, it has the old film camera custom profile.

*cyfoto Thanks!  Can you give more exact instructions?  Open a raw SOOC or a dng saved from LR with the profile in it?  Where is the "Restore color profiles" setting located?  Does this cause the behavior for later "Edit in PhotoShop 2021" invocations from LR to work as expected?  If it is a one-time solution (meaning how to open a single image with the profile), then Open as Smart Object also works.

Use ps open a RAW with ACR，and “Restore the color profiles settings”. It's solved this Bug when the ps open and close normally. But In macos,if force close the PS,then the Bug will be back. 

@andrew_rodney @arjun_haarith I am giving up further troubleshooting for now.  I downgraded to ACR V12 and everything is working just fine.  I hope the next update to ACR 13 fixes this though!  This is clearly some kind of bug in ACR (not my color settings, not the GPU, not my computer, not the display profile, not the color profile itself - something wrong in ACR).

For those who need it, ACR v12 installation is here:  https://helpx.adobe.com/camera-raw/kb/camera-raw-plug-in-installer.html

I am giving up for now.  I downgraded to ACR 12 and everything seems fine.  I hope the next update to ACR 13 fixes this though!

I just did the same.  Downgrade to ACR 12 and everything seems fine.  I hope the next update to ACR 13 fixes this though!

Well, the profiles work just fine for me in LR, including opening that .dng, but of course I have installed them.  The issue has never been LR, but only when opening the image from Lightroom in PhotoShop.  I tried using an Adobe profile and the image looks correct in PS, but when I open the ACR filter, the profile just says "color", but perhaps this is normal as I didn't open as Smart Object and the RAW file has been rasterized?  (Not to introduce a whole other topic...)

Got it, something is certainly wrong. It opens in ACR showing the correct DCP profile. It is imported in LR without and LR shows "Missing Profile". Asking to update metadata and preview command doesn't help. So LR isn't supporting this profile for some reason, ACR is. Screen capture from my Mac below. 

Question: IF you use a different DCP profile, say from Adobe, does it work? 

If so, there might be something about this DCP profile that LR doesn't like. 

@andrew_rodney I uploaded to Google Drive.  you should be able to download from there?

Access to Dropbox?

Odd DNG opened as you state, that may be part of your issue but we need the DNG. No, that's not normal behavior.
