Inaccessible boot device after latest insider update this morning (build 21364)

Nothing works in the recovery mode as it cannot back out the update, cannot repair. 

One of the update is kb5003399 and I forgot the other one, will have to boot back to the command prompt.

In the command prompt, I can tell it's not showing my 1TB drive, it's in x:/ with very little space.

Also, wusa.exe doesn't exist in that command prompt. 

Can anyone help to get my system booting again?

    same problem here for the past few days to almost a week.

    Gigabyte X570 i Aorus Pro WiFi

    Ryzen 3900X

    Radeon 5700XT

    Advanced Micro Devices, Inc. - SCSIAdapter - 9.3.0.221 - Keeps installing.

    I ended up wiping the whole drive and installing Fedora until this mess is fixed. 

    Microsoft really need to pull their finger out because Windows 10 is getting worse with every update, if I didn't play games, I would absolutely not use this junk full stop!

    I skimmed through most of the replies on here, from what I saw it seems mostly everyone with this issue is running a Gigabyte X570 motherboard right?

    Same. I got into a boot loop and automatic repair did not fix it. I was able to uninstall the SCSI adapter driver by using dism in the command prompt recovery mode option, then I was able to boot.

    Gigabyte X570 Aorus Elite Wifi, NVME Samsung 980 Pro is my Windows drive.

    The "Advanced Micro Devices, Inc. - SCSIAdapter - 9.3.0.221" update also negatively impacted my system. Gigabyte X570 Aorus Ultra (BIOS F33h) running Win 20H2.

    After installing the update and rebooting, my system powered down during Windows boot multiple times. Windows then entered a repair mode, resolved the issue automatically, and I am now back in Windows.

    Thanks. I followed your suggestion and will keep my drivers updated manually going forward. This update is a complete joke.
