Secure connection error when sending emails/telegrams

Hello,
with the recent update to version 3.7 I am getting errors when sending emaila and telegram messages.
This error did not happen until recently, that's why I relate it to the version update, although I don't know for sure if that is the cause.

I attach below a sample code. Please set the email addresses, chat id and bot token with your own values.

The error when sending emails is that the SMTP server requires a secure connection.
The error when sending a Telegram message is that it cannot create a secure channel SSL/TLS.

Any help is appreciated.
Thanks!!
