Nav mesh volumen does not work in 4.21.1

Hello, I have placed the nav mesh volume and now it does not work for some reason, I have also tested this in the 3rd person template and it does not work either, it should be a problem of version 4.21 because in previous versions it has always worked.
It also does not show the green color when activating the vision of the navigation, and the npc do not work.

I just downloaded 4.20.3 and there it works.
It is problem of 4.21.
I have already reported the error.

Hi, I’ve been testing the weekend and it seems I owe an apology.
The problem was that I had the collision with vehicule disabled, which is what made the nav mesh detect the ground, and that’s why it did not work, I just saw it right now.

In what way exactly is it broken? I updated from 4.20 to 4.21 and my packaged game’s nav mesh doesn’t generate at runtime correctly. It seems to be ok in editor most of the time but packaged is not.

so did you set vehicle to block and all the rest to ignore ?
