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 issue, boot loop after Windows installed "Advanced Micro Devices, Inc. - SCSIAdapter - 9.3.0.221"

    • MB: Gigabyte X570 AORUS ELITE ATX AM
    • CPU: AMD RYZEN 9 5900X
    • GPU: EVGA GeForce RTX 3080 FTW3 ULTRA GAMING
    • Memory: 32 GB (2 x 16 GB) Corsair Vengeance LPX DDR4-3600 CL18 Memory
    • Drive: Corsair MP600 Force Series Gen4 2 TB M.2-2280 NVME Solid State Drive

    The built-in Win10 startup repair was able to automatically fix the issue and allow my system to boot. Seems like a red-flag event, may want to pull this update as it looks like I'm not the only one experiencing this.

    I can't boot after I install Advanced Micro Devices, Inc. - SCSIAdapter - 9.3.0.221. Please pull this broken update. Also, I am not in the insider program, so that means this update was pushed to the public. Pull this immediately.

     This update should never been given out by Microsoft in the first place. I just spent over an hour trying to get my system back running again. I had to do a system restore point to get my computer to boot again. Microsoft please I can't afford my computer to be down because someone didn't check these updates.
