Hi @user572,
(1)
Can you please share the results of:
dpkg -l | grep hailo
and:
pip list | grep hailo
(2)
We know there was an issue with recent apt update but it was fixed:
Cannot find tappas-core version 5.1.0 - #3 by Michael Maybe you still have the mixed versions.

Anyway, complete uninstall:
Raspberry Trixie Error with Guide (Pi 5, AI Hat 2) - #18 by Michael and then manual installation of Debians and Wheels obtained from our developer zone is always an option - however we suggest using the official way: https://www.raspberrypi.com/documentation/computers/ai.html
Thanks,
