Acrobat DC don't launch at all

After a regular install from Adobe CC, Acrobat DC never go further than a short attempt before just abort any starting. Beside, I have Premiere and Audition perfectly working on this Mac (Monterey 12.6.6) and most other Adobe apps running fine on other computers (mainly PC/win10), including Acrobat.

Adobe support team has driven a remote session and tried (as I did several times) clean re-installs, that have been all unsuccesful, also with former versions. They've also sent me an email with instructions to erase all adobe apps & files, and re-install Acrobat on a totally clean system : no more success.
The console logs report always the same fault :

"Termination Reason: Namespace SIGNAL, Code 11 Segmentation fault: 11
Terminating Process: exc handler [3847]"

Any idea of what could be wrong in my case ?
Thanks in advance for your kind attention - Chris
