OnePlus 7 Pro Device critical unlock not working? TWRP booting not working?

[i_pk_pjers_i]

Hello,

I unlocked my OnePlus 7 Pro bootloader with "fastboot oem unlock_critical" however, it says that Device critical unlocked is false:

Does anyone have any ideas why this might be the case? Does anyone have any ideas of things I can try? As far as I know, this means I won't be able to flash a boot image? Or, is this normal?

Also, when I try fastboot boot twrp-3.5.2_9-0-guacamole.img, it just gets stuck on "Fastboot Mode" logo on my phone:

I'm on the latest Android 11 OxygenOS. Is TWRP 3.5.2_9 not compatible with Android 11?

Thanks.

Ended up installing LineageOS recovery with fastboot flash boot LineageOS recovery zip then adb sideloading copy-partitions.zip then adb sideloading LineageOS zip then adb sideloading MindTheGApps then fastboot -w, booted into LineageOS for the first time and it all just worked, then flashed magisk (also from LineageOS recovery) and it all works.

It does seem like TWRP doesn't work with Android 11 on my OnePlus 7 pro, I'm not sure.

So I guess this was solved, and it doesn't matter that Device critical unlocked is false for me?

For anyone else experiencing it currently. I ended up doing this as well and everything just worked accordingly again.
