Camera raw 14.0 loses Crop Tool Rotate if XMP is embeded in DNG
Adobe Bridge 12.0.0.234 using Camera Raw 14.0.0.950
Windows 10 Pro for Workstations 20H2 OS Build 19042.1348
In Adobe Bridge set Camera Raw Preferences to embed XMP in DNG file.
To reproduce fault.
Double click on a DNG file you want to rotate.
Select Crop Tool and Click on Rotate 90 degrees icon (CW of ACW). The photo rotates.
Click on Done.
Image Preview is not rotated - double clicking back into image shows the photo is not rotated.
In Adobe Bridge click on rotate icon (CW or ACW) - preview rotates.
Double click on image to start in Camera Raw and image is not rotated.
Click on Done and Adobe Bridge preview is reset to not rotated.
However, if you set Camera Raw Preferences to Always use Sidecar files and follow the same sequence the image rotates and stays rotated.
Set the preference back to embed XMP in DNG and the fault returns. So the problem must lie in writing the XMP into the DNG file.
This was working up until the latest update.
I have tried DNG files from two different sources: a camera and a scanner and Adobe Bridge/Camera raw shows the same bug with both.
I have seen one other instances of someone reporting a similar fault.

All the other options in raw I have tried work and the changes are retained.

For me this has been resolved in Camera Raw 14.01 update today.
