Hello @luanxp,
This is very unusual. Can you share more details regarding your operating system? I ran a fresh install of PXC 8.0.32 yesterday on CentOS 9 Stream without any issues.

Hello @luanxp,
Thanks for that info. Unfortunately, that OS is not one of our supported OSes. Glad you figured it out.
