Version 18 was many hundreds of Manager updates ago. Since then, Gmail has tightened its security procedures several times. The macOS has been updated many times. Many things could have changed, especially if you allow automatic updates.
I can tell you with great confidence the problem does not lie with Manager. More people seem to have trouble setting up Gmail than any other mail provider mentioned on the forum. But they eventually get things sorted out.
Speaking of no-brainers, did you Update your email settings in before testing?
