Why Does My PC Stay On After I Shut It Down?

I've got a Windows 11 PC, and I've been running into a strange issue. When I try to shut it down, the monitors turn off, but the computer itself doesn't power down. Instead, it just stays on, and I end up having to hold the power button to force it off. When I turn it back on, everything seems fine again. I'm curious if anyone else has experienced this and if there's a way to fix it? I'll try to capture it on video next time it happens. Thanks for the help!
