MacOS 11.3 update stalled

Hello,

This morning I began updating my M1 MacBook Air from MacOS 11.2.3 to 11.3. The update stalled out at 15 minutes remaining and sat there for approximately 20 minutes. I closed the laptop because I had to go to work. Later in the day, I tried to restart the update (as in, it no longer showed that an update was in progress), and now in the System Preferences Software Update pan just shows the progress bar and a tiny bit of blue on the left end with no information whatsoever (i.e. no "preparing update" or "15 minutes remaining").

I've tried restarting the computer multiple times.

Thanks for any help!
