Tank integrity is intact (no crack), but liquid oxygen is still causing trouble:
"While liquid oxygen loading into the interim cryogenic propulsion stage continues and core stage tanks continue to be replenished with propellants, engineers are troubleshooting an issue conditioning one of the RS-25 engines (engine 3) on the bottom of the core stage. Launch controllers condition the engines by increasing pressure on the core stage tanks to bleed some of the cryogenic propellant to the engines to get them to the proper temperature range to start them. Engine 3 is not properly being conditioned through the bleed process, and engineers are troubleshooting." source:

Launch window is slowly closing.
"NASA has a two-hour window in which to launch Artemis 1 on Aug. 29. That means the launch could occur anytime between
8:33 a.m. and 10:33 a.m. EDT (1233-1433 GMT)" source:

"There are two backup launch days in Artemis 1's current flight window:
Friday, Sept. 2 and
Monday, Sept. 5. Both dates have their own extended launch windows.
If NASA is forced to go for the Sept. 2 launch date, the Artemis 1 SLS rocket will launch at
12:48 p.m. EDT (1748 GMT) and would have a two-hour window to get off the ground. NASA would have to accept a shorter mission, 39 days instead of the 42-day flight an Aug. 29 liftoff allows for, if the agency opts for this launch date. It would splash down in the ocean on Oct. 11 instead of the original Oct. 10.
The Sept. 5 launch date calls for a liftoff at
5:12 p.m. EDT (2212 GMT). The launch window for this date is a bit shorter, 90 minutes as opposed to two hours, but does allow NASA to pursue a longer 42-day flight. Landing would occur on Oct. 17."
