TWRP failed install on 3a XL Android 9 - Google Pixel 3a XL Questions & Answers

I have been trying and failing to get TWRP installed on my Pixel 3a XL running Android 9 stock image
Trying the recommended install instructions from the TWRP website, I keep getting the following error;
Code:
C:\platform-tools>fastboot boot twrp.img
Sending 'boot.img' (65536 KB) FAILED (Write to device failed (no link))
fastboot: error: Command failed
C:\platform-tools>fastboot recovery twrp.img
fastboot: usage: unknown command recovery
C:\platform-tools>fastboot flash recovery twrp.img
Sending 'recovery' (65536 KB) FAILED (Write to device failed (no link))
fastboot: error: Command failed
I have ensured the bootloader is unlocked, I have updated drivers from the OEM package, I can see devices properly with fastboot and adb, and I've even flashed stock images with fastboot. I've tried looking up this error, but all results point to solutions that don't work, or deleted posts. If anyone has some insight, I'd very much appreciate it.

Update to the latest version of Android or try an older version of TWRP. The latest version of TWRP doesn't like Android 9 (possibly other versions as well).

I believe this was the last update for twrp on android 9

Mi Mix 2 won't accept TWRP

Hi all,
I am getting a headached with my mix 2 ......
Bootloader is unlocked (shown in Developer Settings and as little text when entering Backup/Fastboot).. I tried different Versions of fastboot from an old version 1:7.0.0+r33-2 to an new one -> fastboot version 28.0.0-4797878.
MIUI Version: 9.6.1.0(ODEMIFD) (Stable)
And yes I did it like the manual here on xda for this mobile ...
I also changed the System from Windows 10 to an Kali....
There isn't a single line of output.
Trying to directly boot the TWRP Image stucks at the first line telleng me: Downloading 'boot.img'
Someone can help me?
Friend here who helped him:
Even just listing the variables didn't yield any output (download got stuck on the "getvar: stuff, too)

EDIT:
It worked, i changed to my laptop(win 10). I used a git bash(random used this), no usb devices are connected and no internet.
Just typed .\fastboot.exe flash recovery twrp.img
It worked
Warning: Only reboot to Recovery and install the .img with the "temporary" again, if you don't Xiaomi will place it's own bootloader again there.

Unable to flash TWRP after flashing factory image (Not allowed to flash (recovery))

I wiped my device and flashed the latest factory image. I am now trying to install TWRP but fastboot returns the following:

./fastboot flash recovery ./twrp.img

The bootloader is unlocked, and I have tried relocking and unlocking it to no effect.

As already noted, TWRP has never worked with 10. If you are on 9 then head over to the dedicated TWRP thread and get yourself up to speed.
if on android 9 it would be fastboot boot twrp. img. (if on Pie)
A/B slot devices don't have a dedicated recovery partition. (reason why flashing to recovery didn't work)
Android 10 doesn't have working TWRP yet. ( can't decrypt data or something)

From what I have encountered, you can not install TWRP on the Pixel 3 XL. Only thing I have been able to do is root it with Magisk
