Umbrel won't shut my node down

From umbrel.local/settings, I choose “Shutdown” (upper right in red) and it goes to the message screen “Don’t power down or unplug… till shutdown” or words to that effect. It will stay there forever and I have to risk my hardware by unplugging the node. Even the on/off button doesn’t do anything.

Pi5, 1Tb nVME, latest updates.

Thanks all!
