Model T 24 word help

I have the trezor model T The website method only lets me do 12 words or shamir. So you have to install phyton and all this other crap to try to reset and install with 24 word.

I installed phyton and trezor bridge like the guide said. I tried using this setting and I get this error

C:/users/IEUser>trezorctl reset-device -t 256
or
C:/users/IEUser>trezorctl reset-device -p -t 256
or
C:/users/IEUser>trezorctl reset-device -t 256 -p

and none of those work and I get

Blockquote
C:\users…\appdata\local\programs\python\python37\lib\site-packages\trezorlib\toif.py", line 5, in
import attr
ModuleNotFoundError: No module named ‘attr’

How do I get 24 word passphrase on Trezor Model T?

Extra Details:
pip version 19.0.3 I didn’t upgrade it because I didn’t want to glitch/break anything

EDIT: I did the upgrade command to 21.1.2

I still get same error even after upgrading

EDIT: I tried just wiping the device through website portal in advance settings and I keep getting this error:
"Wipe failed.

Error details: Device used in another window."

Why can’t I just wipe it and switch to shamir and forget this cmd command line BS?

import attr
ModuleNotFoundError: No module named ‘attr’

use pip install attrs to resolve this problem
