This is because Google has depreciated ARC. Try with an older version. Like chrome 74

But not above Chrome 74 as it does not support arc.

Only download chrome from trusted site else I'm not responsible what happens to your pc.

Do you mean 54? I can't find my source anymore but I remember reading about ARC support being removed from all versions except ChromeOS after version 54.
