Thank you!
]]>I have searched information about "Great Wall, China, ..." The problem still exists.
Actually, the epic browser (Version 81.4.3991.125 (Official Build) (32-bit)) in my another computer with not latest Windows OS (OS Edition: Windows 10 Education, Version: 1909, OS build: 18363.1679) works fine.
I doubt the problem is from the compatibility with the newest Window 10.
