I submitted this under BOSL but i think it may apply here.

I am using the latest version of OpenSCAD downloaded 9/17/2020.

Running 64 bit version on windows 10.
version 2019.05

Use the following code:

use <BOSL/involute_gears.scad>

$fn = 360;

gear(mm_per_tooth=10, number_of_teeth=64, thickness=8, hole_diameter=6);

Execute render above and rendering will show nothing. If i change to 32 teeth, it works fine.

Any guidance?

Error in console as follows:

Are you able to reproduce with BOSL2?
