sudo su - with error su: failed to execute /bin/bash: Permission denied

I have a Red Hat Enterprise Linux Server release 7.7. Local user created. Sudoers file configured with ALL = (ALL) ALL for the user. The user can execute any command, like: sudo ls, sudo cat, sudo wherever.

However, the following command does not work: sudo su -It receives error message:

Last login: Tue Jun 15 10:21:52 -03 2021 on pts/1
su: failed to execute /bin/bash: Permission denied

I've already checked files and directory permissions.
