Macbook air restarts in sleep mode

I get repeated notices that my computer "was restarted because of a problem" when I awaken it after the lid is opened or after I manually put it in sleep mode. The report says "Intel crashLog recorded due to unexpected reset." I've never seen this issue on any previous Macs and I can't find any solutions online.

Computer is a 2020 13-in Air running Big Sur.
