Same. Went to boot up R16 this morning (after reluctantly allowing that Apple iPhone update) and then c4d suddenly won’t open. Get one slight bounce in the dock then it disappears. Tried the reinstallation iso file and it’s strangely not working also.
Doing a Restore from Time Machine backup right now. Any help to getting this fixed (and being able to get back to work) would be appreciated! So frustrating..
