mmm ... This is an odd one! The fact you see the curser on the screen tells us the touchpad input via the T2 chip is working and the input to the Intel graphics engine is working (if you see the movement as you move the curser) as well as the internal displays input and its display as well. That only leaves the main processor logic which appears to have failed.

Lets did a bit deeper here can you get the onboard diagnostics working? Lets do a forced shutdown by holding the power button down for a good 20~30 secs, release the button and now press and hold the ***D*** key and press the power button again to enter into the onboard diagnostics. Did it enter? Did you get any errors?
