Install Exception-Linux Mint-libGL error: MESA-LOADER

Greetings to All:
linux Mint 21.3 - Acer Laptop “An exception occurred during fetch of list of sys display settings.”

libGL error: MESA-LOADER: failed to open iris: /usr/lib/dri/ - no such file or directory
(search paths /usr/lib/x86_64-linux-gnu/dri:$${ORIGIN}/dri:/usr/lib/dir, suffix _dri)

Above detail repeated once again for iris_dri.os and once for files can’t be found or wrong version?

navigator appears and and seems to operate. (base) prefix appears in terminal. Both of these files exist on the system and appear at /usr/lib/x86_64-linux-gnu/dri/. Not sure what is going on but looking to get a clean install. Entire installation instructions followed closely.

Thanks in advance for any and all comments or suggestions. John Adcock
