@memsharded Thanks that helped me to solve the issue. The problem was in --ignore-installed flag I used to reinstall conan.

So to reproduce:

pip install conan==1.51.0 # or any other earlier version
pip install conan==1.52.0 --ignore-installed
conan --version # this crashes

without --ignore-installed flag everything works.

Hope this will help someone else =)

Hi @SergeyKrivohatskiy

It seems that some updates to 1.52 are not completely cleaning the previous stuff and something breaks. Can you please try installing a fresh Conan in a clean Python virtualenv (or maybe trying pipx), and see if the problem still reproduces?

Hi @Zvicii - thank you for reporting this issue. There was an issue with the wayland recipe in conan-center-index where a private Conan API was used, and it changed internally across Conan versions. We are tracking this here https://github.com/conan-io/conan-center-index/issues/12722 as an issue related to the recipe - which needs to be fixed.
