If it was network error, it would show error in all the browsers.
To test if it was network problem, I used a different Internet connection and problem persists in the same way. I doubt that it is network problem or PC problem.
The problem may be related with Chromium which is used by both Chrome and Edge.
I’ve created a screen recording, have a look at this, it will clarify the problem.
The left side browser is Microsoft Edge and right side browser is Safari
