Just wanted to post this in case of anyone else having some issues updating their Xiaomi device to MIUI 13 (I have an Mi 11 Ultra).
When I tried installing the new MIUI 13 fastboot update I got the following error in cmd:

Sending sparse 'super' 7/9 (781156 KB) FAILED (Error reading sparse file)
fastboot: error: Command failed
fastboot: error: Device does not support slots

It seemed to fail on this step specifically and then the terminal closed and the phone was still in fastboot.
Running the windows_fastboot_update_rom again just opened a new cmd window that closed itself right away.
After restarting the device into fastboot I was able to run the updater again, but it kept failing on the same step and gave the same error message.
I just kept repeating this and on the 4th try it worked. So I am not sure what is causing this but I thought it might help someone.
I have used the weekly updates for about a year now and every update worked on the first try except for this time so it gave me a little scare.

Thank you for the info!
Yes the ROM works fine so that is great. Just thought if someone else also gets stuck with this issue that they might solve it by retrying to run the updater a few times after exiting and entering the fastboot again.

Was not sure where else to post this so hope here is fine.

have the same issue here everytime i do an update ROM fails on 1 of the Sparse 'super' stages, i use to think i'll have to do a clean install everytime but multiple tries and it seems to work one after abit.

has it got anything to do with Magisk and the boot.img shall i unroot first maybe?

Everything is fixed. Connect phone to pc again and it's recognized as fastboot device.
Run the windows_fastboot_update_rom several times until installation is finished.
