Webshop & Account LogIn doesn't work

I was trying to Log-In into my Account and to Download my Stuff, unfortunately the “My Account” Site and the Webshop are just two white Pages.
This happens on MacOS in Firefox and Safari. :confused:

Mac Mini late 2020
MacOS Monterey 12.2
Safari 15.3
Firefox 96.0.3

I also tried this on an IPhone 8 on Safari (same result).

Screenshots from MAC:

Hi Niklas,

Thanks for letting us know!

We’re getting to the bottom of this right now.
