Your /usr/bin/sudo executable has either a wrong owner or permission set.

No matter which one applies here, the following two commands should fix it:

pkexec chown root: /usr/bin/sudo 
pkexec chmod 4755 /usr/bin/sudo

After that, sudo should be working normally again and you will be able to use it to run fdisk with root privileges with it.
