Pixel 3 won't let me flash anything

[vickmen]

I have official android 11 without root or anything but it does not let me flash anything or boot and it tells me the fastboot of the mobile that is in the slot: B

PS C:\Users\vickd\Desktop\blueline-rp1a.200720.009> fastboot boot TWRP.img
downloading 'boot.img'...
OKAY [ 2.548s]

TWRP has not worked on Pixel 3 since Android 9. There is a test build for Android 10 at https://forum.xda-developers.com/pixel-3/development/twrp-3-2-3-0-pixel-3-t3861622/page29, but the only response to that post was it did not work. There is nothing for Android 11.
