I don't know if it is the same for Xperia 1 iii, but my Xperia 10 iii has both fastboot mode and fastbootd. Make sure you are booted into fastboot mode as fastbootd won't work.
To boot into fastboot mode:
Turn off your device.
Connect a USB-cable to your computer.
On your device, press the Fastboot key (Volume Up) at the same time as you connect the other end of the USB-cable.
Did it work?
If not, we need more info. Please run fastboot oem device-info as administrator in cmd.

same out out as above
