Did you 'fastboot reboot bootloader' first before the boot attempt? You need be in the Fastbootd, not the normal Fastboot screen. I know it's odd, but that's how I got mine. Because apparently fastboot itself won't boot even my TWRP but fastbootd does. The device being an A/B device is the only reason to ever use fastboot (not fastbootd), to flash the sparsed system image is my understanding.
Never mind, figured out how to get into Fastbootd, how do i boot twrp in fastbootd?
