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?

    This update seems to be the culprit. What's the solution though? How do I stop it after reinstalling windows.

    Same here. Windows installed SCSIAdapter - 9.3.0.221by itselfe and asked for reboot.

    After reboot - inaccessible boot device.

    Win install USB and fix startup (twice) resolved the issue.

    3700X, x570, NVMe pcie 4.0

    Edit:

    No insiders program

    Several RGB, realtek, bitdefender and whatnot software needed new login, wanted new driver install after fixing startup.

    And somehow windows decided to reinstall the AMD SCSI Adapter during the fixing for all the other stuff (although the SCSI update was listed as successful) and again, inaccessible boot device.

    Pause your windows update until someone has a better solution!

    ran into the same problem. <salty comments from yesterday after reinstalling windows 4 times> I was finally able to get wushowhide to show the scsi driver by selecting the Dev Channel, rebooting, and then immediately launching wushowhide. So far it seems to work. 🤸 Using the Beta Channel seemed to always force the driver install, but perhaps I'm an idiot.
