If a paladin that used sacred weapon on a two handed weapon takes one hand off the weapon does sacred weapon dispell

I realise it sounds strange but, if a paladin were to cast sacred weapon on a two handed great sword then use one hand to cast another spell would sacred weapon stop working?

I am having a discussion with my current group about the wording of sacred weapon but my DM argues that because it is a two handed weapon he has technically let go of it to cast a spell because he is holding a two handed weapon with one hand.

"If you are no longer holding or carrying this weapon, or if you fall unconscious, this effect ends."

This is the end condition for Sacred Weapon (Oath of Devotion Channel Divinity):

If you are no longer holding or carrying this weapon, or if you fall unconscious, this effect ends.

It does not require that you be holding it with two hands, only that you be holding or carrying it. So you don't even have to have one hand on it. It can be sheathed on your back and the effect will remain active.
