Just installed, try to update Company details getting error

I just installed Dolibarr on Cpanel via Softacolous. The installation was successful and I am able to log in to the admin panel.
However, I am getting an error when trying to update company information. Upon selecting the country dropdown and selecting a country in the company section it throws an error

Initial install version 18.0.3

Any idea why I may be getting an error?
