zlib.output_compression problem in CI 4.1.4

/app/Config/Events.php
Removing this code in app/Config/Events.php, or turning off output_compression in php.ini is a temp solution.

while (\ob_get_level() > 0)
 {
  \ob_end_flush();
 }

 \ob_start(function ($buffer) {
  return $buffer;
 });

You can just comment it out

Thanks @devprecious, I did that before, and it made no difference.
Still trying to find a solution though.
