Cannot export nested blocks to .dwg anymore since rhino update

Dear all,

Since today I cannot export nested blocks to a .dwg file anymore.
I tried several (very) different (2D) files that used to be fine for exporting, but none of them work now.
All nested elements are gone in the exported file, only ‘top-layer’ blocks still exist.
It seems to have been caused by the latest rhino update that I installed today.

Does anyone else encounter this issue, and if so, is there a way to fix it?
Thank you in advance!
