Xvnc Illegal instruction Server Aborting

I installed Tigervnc on my server yesterday, it was working, but today I did general package upgrades and rebooted the server. Since then tigervnc fails to start

I've tried re-installing tigervnc and its dependencies, but it is still happening.

Anyone as suggestions for moving forward, there doesn't appear to be anything useful in the error log to narrow down the issue.

Yes, apparently that is exactly the issue.

Downgraded to mesa-19.3.3-1-x86_64 and I could start the VNC server.

Thank you.
