There were 3 possible reasons for this

The email address you are sending to is incorrect.
The recipient's email server is rejecting emails from your domain.
Your email is being blocked by a spam filter.

also on checking your message, I can see that you are using office 365 service if I am not wrong, you can refer to this microsoft blog to fix thiss issue Fix NDR error code 550 5.4.1 in Exchange Online - Exchange | Microsoft Learn also I suggest you to refer to this gmail thread too get quick resolution 550 5.4.1 Recipient address rejected: Access denied [BO1IND01FT005.eop-IND01.prod.protection.outlook - Gmail Community (google.com)

No this won't cause any issue find the image below both shows emails emails got rejected by microsoft so there's no issue from Gmail side, you need to contact Microsoft Email support to get this issue fix.

What is your domain name? The images you posted suggest that your domain has been set to deliver mail to Microsoft, not Google.
