2D colliders not working on Build versionb

Hi all I build a 2D game and the 2D colliders are not working I can not figure out what is going on.

This is the inspector of one of the 2D colliders. The triggers don’t work, but just on the Build version on the Editor everything is working fine. Any Clue?

No idea. How have you verified it’s not working?

What’s “versionb”?
