Input issues in build

Howdy
I have some problems with my inputs which only happens in a build and it seems that it only affect the gamepad inputs.

Both sticks and all axis are working fine but when I open the inventory I'm not able to control it. No focus on the slots.
This all works fine in the editor.

And this do not happen all the time. 1/10 builds are working correct.

So how can I track this down? Can this be a xinput problem?

5.6? I've noticed a few times in my rpg melee pack projects the same issue, no sign of the square highlight and often chooses the 4th slot on a row if any. And this is in the editor preview every once in a while.

Do you have a EventSystem in the scene?
