navi 2 won't fast boot?

I am trying to root/twrp/gapps my childs nabi 2 and my computer recognizes the device. Howerver each time any of the root tools being used restarts the device it freezes there. I have tried the 2 different types of device drivers, and If I go to device manager, I right click to update drivers and it gives me this error:

go in setting about tablet and get Model Number, Edition and Andoid version.
mine says
NABI2-NV7A
NABI2-NV7A-US
4.04
having the wrong gapps will cause errors

Stop using toolkits. Most of us can't help you if you do so.
Follow the thread in my signature which says 'unlocking bootloader and rooting the device'. In that thread, read the first part. If you do what it says exactly, adb and fastboot must work.

Can I install official TWRP right from plays store in a OP8 (IN2015) ??

Hi ! I have a OnePlus 8 IN2015 with bootloader unlocked but not rooted , I understand the official TWRP recently added support for this device (instant noodle)
My question is can I just hit download TWRP and follow the instructions and be done straight from the phone ? Do I need magisk first ?
Also when I click the drop down menu to search for a device it says failed to connect to the server ?

It's been quite a while since I've flash anything on my devices but none of this is new to me, I just been feeling the itch to start flashing stuff again, I just wanted to be completely sure before flashing.
