Let's be clear: The World Over Canon isn't all-powerful. It has 2 solid limitations, and potentially a third.

1st: The obvious one, the Stand needs to directly touch something with its hands or fists in order to overwrite it. This isn't that much of a limitation to DIO other than limiting his immediate range, which is more just delaying the inevitable.

2nd: DIO cannot use The World Over Canon to change his own ability or remove it's limitations, only his own. He can't make the time-stop last indefinitely, since that's a limitation tied to his Stand. But he can overwrite his own body to have infinite stamina, so that it effectively seems like he can hold the time-stop indefinitely. It is explicitly stated that The World Over Canon can't change its own limitations.

3rd(?): DIO in EoH has some weird obsession with absorbing souls, under the impression it will somehow make him stronger. It's possible that The World Over Canon requires souls as a sort of fuel, but it's left really unclear so we'll ignore this for now.

Already we can see why GER should've beaten The World Over Canon in EoH. DIO needed to make direct contact with GER in order to make himself immune, while GER doesn't require direct contact to use RtZ. Yet for some baffling reason, Giorno decides to engage with DIO directly and allows himself to get hit.

But this is why EoH isn't canon anyway.
