Not Receiving Gmail Calendar Invites in Outlook

I am not receiving calendar invitations in my Outlook email when they are sent from a Gmail account. I am able to receive regular emails from the same Gmail account without any issue, but calendar invites sent from that account do not appear in Outlook.

I have confirmed that the sender is on the approved/safe sender list, and as noted, regular emails from this sender are being received successfully. The issue seems to affect only calendar invitations.

Could you please help investigate why calendar invites from this Gmail account are not being delivered or appearing in Outlook?
