Xref Camera not renderings via DR nodes

[FLP]

All of a sudden when I have a camera (vray) loading from an Xref the DR buckets render black. If I merge the camera into the scene it renders as expected. This seems to not be file specific but related to my workstation.

MAX 2020 & 2021
Vray 5.00.05 00001

EDIT:

It appears this issue has occurred before with other users in the past. It started for me a weekago.

Yes, it is a known issue as already posted in the linked topic (internal bug-tracker id: VMAX-1242). I'll raise its priority additionally. For now, merging the camera is the preferred workaround.
