Creative core pathway checkpoint not working

Hi to everyone who reads this!

I can’t complete the last step of the creative core pathway, the pathway checkpoint.
The “Mark step as completed” and the “Save and preview submission” buttons do not work for me.
When I look at the network console with F12, I can see that when I click any of the buttons mentioned on the pathway checkpoint the reply for the POST request made is 404 not found.

I just wanted to report this, the world will not stop working if this does not get fixed.
