This happened to me aprox. half a year ago. I thought it was just my browser because edge and chrome worked fine. But yesterday I reinstalled windows and it happened again.

Using Opera 60.0.3255.109 64-bit.
There's a browser identification I found:
Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.103 Safari/537.36 OPR/60.0.3255.109
Also the stacktrace:
Code:
Uncaught DOMException: Failed to read the 'localStorage' property from 'Window': Access is denied for this document.
