WTF ..
Download latest official fastboot rom , take official recovery from there ..
Then try the same thing .. and remember DO NOT flash the img only boot ..
fastboot devices
fastboot boot recovery.img
When it boots to official recovery probably you will not have touch issue ( works with buttons ) ..
Wipe all data and reboot to system ..
Edit
You have to know that everything will be lost ..
EDIT 2
You can still try to find a workable twrp though ..
EDIT 3
You can also flash a fastboot rom and start from scratch ..
Edit 4
I just try to find the quickest solution to your issue cause i never faced such an issue on my poco , neither with 0623 twrp nor with 0328 twrp..
first thanks for the help, if all is lost then.....
