We are also experiencing this behavior - the list modern web part is not returned by the API and this causes problems on our end.
I heard that MSFT engineering is aware of this & they are investigating.
FYI - they'll update this thread if they have an update
The root cause of the problem has been found and a fix is rolling out soon.
