How did you resolve it?

It was a CSS configuration on my end. The strange thing is that it only affected Google Chrome.
I had this to center the grid's checkboxes columns in the web2py-bootstrap4.css

.web2py_grid_wo input[type="checkbox"] {
    text-align: center;
    width: 100%;
}

And that was causing Google Chrome to not show the selection checkboxes. They were there (in the HTML code), they simply were not shown.
I added this to solve it.

.web2py_grid_wo input[name="records"] {
    text-align: left;
    width: auto;
}
