Eventually, yes, but not because of the creation of a new crater on the
moon.

 This article
<https://www.sciencenews.org/article/moon-grand-canyons-lunar-rocks>
might be relevant, if the impact of the asteroid in question would
produce enegergies less than or greater than "130 times that of the
global inventory of nuclear weapons". Just as providing a sense of
scale to the possible results.
 But it still only a 4% chance of a hit. That's a 96% chance of a miss,
after all.
 Note: I signed out while finding this, but it should be generally
available. If not, the point of the article is that it took only 10
minutes to create two canyons deeper than the Grand Canyon by tossing
rocks around.

Just to clarify. The Schrodinger Impact Basin, which the article
refers to, is 312 km across. This is 50% larger than the Cicxulub
Crater the ended the dinosaurs, which was crated by an impactor
10 km across.
The current asteroid, 2024 YR4, is about 60m across, and about
one five millionth the mass of the Chicxulub impactor. Its a city
killer, not something that would cause a mass extinction.
