Roll Skill Not Working

I've been experiencing an issue with the roll skill for a few days now. I play on Xbox Series S.
When I press the button, I can see it being triggered on the game interface, but the character doesn't roll.

I tried assigning the skill to a different button, but that didn't help. I also tested other skills on the same button, and they worked perfectly, so I don't believe the problem is with the controller.

I have already uninstalled and reinstalled the game, but the issue persists.
The roll skill is the only one that is not working properly.

Thank you for the reply! Yes, I am using the helmet Ezomyte Peak, Soldier Greathelm, which grants Unwavering Stance.
