I then (just now) rolled back and nothing changed for either Bluetooth or VPN, I assume this means that the problem isn't the update.
Addendum from the next day, after many reboots, now without doing anything, the Bluetooth has started working well again, I can't really explain it, but just the same.
So, in the hope of giving a useful feedbeck,, the only remaining problems are OpenVPN which stopped working (but maybe I solved it differently...and problably it's not correlatated to the update ) and ZED which I don't use, but it still doesn't work (x @joebonrichie : I just read it today, I didn't realize the answer.... I use KDE in Xorg, never even tried wayland for a calibration issue of the screen).
