Hotmail account cannot receive emails from google (gmail.com)

At some point today, my personal hotmail account stopped receiving emails from the gmail.com domain.

I can send to gmail.com recipients no problem, just cannot receive from them. I have both "gmail.com" and "******@gmail.com" in my "safe senders" list. There are no emails from them in my junk folder either. They did not report any "bounce back" emails either.

I am Microsoft 365 subscriber and I am paying for this!
