[MCU] Why didn't Captain Marvel snap away Thanos?

She is much stronger than Hulk or Thanos (maybe even combined) and absorbing radiation is kinda her thing. If any of the Avengers could use the Infinity Gauntlet without repercussions it would be her.

The mission at the time Carol had it was playing keep-away.  They were planning to fling it into the quantum realm using the portal in the back of the van, not snap Thanos away.  The goal was to get it to the van.

It only got to that point of Tony snapping when that original plan failed and Tony's snap was the last ditch effort.  By then, however, Thanos had the gauntlet on his hand and Tony had the stones which he fashioned into his own nano suit.  There was no further opportunity to get the gauntlet off of Thanos' hand and the stones to Carol.
