Dear brian!

Thank you,

I fix it by one of my friend.

WHMCS using "laminas" that it did not update after PHP 7.2 and older and not working with PHP 7.3 or higher.

I put solution for any body need fix this:

Go to: WHMCS/vendor/laminas/laminas-httphandlerrunner/src/Emitter/SapiEmitterTrait.php

in line of 39 , 40 and 41:

if (ob_get_level() > 0 && ob_get_length() > 0) {
     throw EmitterException::forOutputSent();
}

Change to:

if (ob_get_level() > 0 && ob_get_length() > 0) {
     while(ob_get_level() > 0){ob_end_clean();}
}

Just do it! it's fixed and resolved.

Are you sure both PHP versions have the same modules enabled? Sadly, when errors from encoded files, only WHMCS can help you as we have no way to look at the specific line and what is causing the error. You should open a support ticket if errors come from the vendor library files.
