NASA's crew on the International Space Station took temporary shelter inside a Dragon capsule. This precautionary measure was taken due to repair work on the space station. The crew members involved were from the SpaceX Crew-12 mission and another NASA astronaut.

The issue prompting the repair work involves leaks in the Russian segment of the space station. Specifically, the leaks are in the Zvezda service module transfer tunnel. This problem has been recurring over the past six years.

Further details about the situation and the repair work are available from NASA and other sources, including Spaceflight Now.
