I've just run into this issue. At first I thought that there was something wrong with the cable or the power, but now stumbled on this thread.
Laptop: 13" MacBook Pro, M1 processor, 2020 edition Display: Apple Studio Display
Update: Running this in the terminal works:
sudo pmset -a disablesleep 1
And if you want to revert that, run this:
sudo pmset -a disablesleep 0
