error -- unsupported GNU version! gcc versions later than 8 are not supported!

Describe the bug
I am trying to compile this project in Linux Mint 20.2.
I am getting the error error -- unsupported GNU version! gcc versions later than 8 are not supported!

The version mu gcc is: gcc (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0

Any suggestion how to fix that without uninstall Linux Mint 20.2?

Here the error log:
