[Solved] What changed in install.py today?!? Worked this morning, Fails now. (v13.1.1 & v13.2.x)

I used this method on two digitalocean ubuntu 20.04 droplets and everything went ok but I have the same issue on both installations:
I am unable to email new POS Invoice Receipt after I Complete Order in the POS System;
When I click on “Email Receipt” it offers me the option to provide the email address.
After I input the email address and I click Send it shows a notification “Email Sent Successfully.” But the email is not sent. When I look at the error logs two new errors are generated as shown below:
one error says “frappe.core.doctype.communication.email.sendmail”
and the other is show in the screenshot below


my installations are as follows:
erpnext 13.9.2
frappe 13.9.1
and
erpnext 13.10.0
frappe 13.10.0

I can send other types of emails from within erpnext meaning my Email Domain (gmail) and Email Accounts are working.

For the sake of the community please reply to the following main thread if you got a solution I can try out.

Please help, thank you in advance.
