Hand skinning is wrong/offset only in play mode with Manny skeleton in UE5

Hi!

I have this character that imports correctly and uses the epic Manny skeleton in UE5. In the editor, when I select and move the different bones, the skinning looks perfect (first screenshot).

But, when I click play and control the character, the hands are offset to the front (second screenshot).

What could cause this offset? Thanks.
