Looks like Artemis is not the only new rocket with scrubbed launches due to gas pressurization issues.

Firefly Aerospace said Monday it will try again Sept. 19 to launch its second Alpha rocket from California after scrubbing back-to-back launch attempts due to a helium pressure issue and unfavorable wind conditions.
The Texas-based company is preparing for the second test flight of its Alpha launch vehicle, a nearly 10-story-tall rocket designed to haul small satellites into low Earth orbit. A test launch last year failed when one of its four main engines shut down shortly after liftoff from Vandenberg Space Force Base, California.
Firefly’s second commercial Alpha rocket was scheduled to launch from Vandenberg on Sunday, but the launch team scrubbed the launch attempt to investigate a drop in helium supply pressure to the rocket’s second stage. The company was ready to try again Monday, but called off the countdown “due to violation of wind constraints.”

We refer to it as rocket science but often it just comes down to plumbing.
