You were right.
It's the Security Level setting in the Mullvad browser.
If you set it to Safer the issue occurs.
Seems to just be blocking whatever is setting the pop-up depth, everything else on the site works just fine :)

Howdy all - it's Mullvad Browser 13.01 on macOS 13.4 not using TOR
I was too lazy to learn screenshots on the mac so I just "printed" it. :D
Here you go -
Howdy,
The Suspicious Activity warning is behind the page content and can not be interacted with and removed.
I've included a screenshot of the homepage, but this persists on all pages.
I reckon the behavior started a few months ago.
My workaround is to close the modal via developer tools...
