Please check these things before submitting your issue:

• Read the error message you're seeing - it often tells you what is wrong, and may contain useful links & instructions
• Make sure you're using the latest version of PHPMailer
• Check that your problem is not dealt with in the troubleshooting guide, especially if you're having problems connecting to Gmail or GoDaddy
• Include sufficient code to reproduce your problem
• If you're having an SMTP issue, include the debug output generated with SMTPDebug = 2 set
• If you have a question about how to use PHPMailer (rather than reporting a bug in it), tag a question on Stack Overflow with phpmailer, but search first!

Code to reproduce

Debug output

[Synchro]

There's not enough info to go on here. PHPMailer does not cause this error by itself, so the problem must lie elsewhere. It also looks like you're running PHP 7.4, which, while it is supported by PHPMailer, is no longer a maintained version of PHP.
