Thank you very much everyone for your help. I think I found the answer on the knowledge base section. I followed the reset actions recommended and at least VW restarts now. My latest file and its backups seem to have issue though.
Here is the link with the knowledge base article (nice to at least get back working):

Again, thank you to everyone for your time trying to help, very much appreciated.
Best to all
