I got a reply on the util-linux issue tracker

https://github.com/util-linux/util-
linux/issues/1704#issuecomment-1144962011

So it seems te a systemd issue.

Title:
  uuidd appears to be broken on Ubuntu 20.04 LTS

Status in util-linux package in Ubuntu:
  New

Bug description:
  uuidgen -t returns a correct result when uuidd is _not_ running. See
  the following transcript

  vdbergh at pl:~/$ sudo systemctl stop uuidd.service uuidd.socket
  vdbergh at pl:~/$ uuidgen -t
  ef485202-e275-11ec-b7ab-448500dea459     <----  (correct: last part is the MAC address)
  vdbergh at pl:~/$ sudo systemctl start uuidd.service 
  vdbergh at pl:~/$ uuidgen -t
  f8e7b3ca-e275-11ec-b074-1d42fae212d0   <---- (incorrect)

  The same issue appears with every program that relies on libuuid.

  Example: uuid.getnode() in python3 is supposed to return the MAC
  address but this only works if uuidd is not running.
