Judging by what you've said I figure you already checked this but Win11 doesn't have the fast startup feature from Win10 enabled by default does it? If it does turning the machine off then on won't actually power cycle it because fast startup causes it to instead enter a deep sleep state. A restart, unplugging and plugging it back in (after selecting "shutdown"), or just disabling this feature and then power cycling the machine would all have the same effect of actually power cycling the machine as you expected.
