You did not addressed John 17:5 by explaining how Jesus could have SHARED glory with the Father before the world was.
You misunderstand Isaiah 48:11 where God says,
"And My glory I will not give to another."
Verse 11 refers back to verse 5 where God says,
Therefore I declared them to you long ago, before they took place I proclaimed them to you, So that you would not say, 'My idol has done them, And my graven image and my molten image have commanded them.'
Therefore, verse 11 means this,
"And My glory I will not give to another idol."
