Microsoft OneDrive no longer detected

Latest (official) OneDrive version 19.163.0818.004, now in "program files (x86)" folder, is no longer detected

OneDrive sync client used to install for each user of the system in the %localappdata% folder; each user had its own version of the client, and each client had to be updated automatically or manually.
Now it's possible to install the client once per machine, in the "program files (x86)" folder. This was done on some of my systems automatically when a new version installed (this version also offered new features for office365 customers), but there's also an option to install the client manually once per machine with the "/allusers" option. The migration of the client from %localappdata% to the program files folder is done automatically.
Once there, the sync client is no longer detected by the program
