Windows 10 new feature 2004 - Crashes

I have Lenovo E490 and I got a notification in windows update that a new windows 10 install and update feature 2004 is waiting, the first time i did, it corrupted install and it asked me bitlocker, after I fixed it, unsure if this feature was the cause, I have installed new feature and then my windows crashed while configuring and crashes at (See attached)
with Stop code: SYSTEM SERVICE EXEPTION
what failed: MFEHIDK.SYS

Now I when I go to advanced and whatever I do like 1. command prompt 2. Restore 3. Uninstall feature it is asking me windows password which it does not accept. Any help will be appreciated and I have many applications running and do not want ruin many months of data for Microsoft blunders

1. I tried to put in the backupimage drive and in advance option wanted to boot from USB ( not boot manager) it does not work, it goes back into windows
2. I created a USB linux bootable drive and used boot manager, it detects the USB, but when I select and " Enter" the selection goes back to inbuilt

Please can you help me to the Command Prompt so that I get rid of password as per the instructions available in net.
Any help is appreciated, I called lenovo and microsoft both wanted me to do factory reset with files .. very last resort

Your help will be greatly appreciated.

@FreeBooter and @zbook thanks a lot. I am not able to get into 1. Command Prompt 2. Uninstall feature 3.Restore or I am not able to boot via USB linux so that I can remove password.
1. Windows is asking me to enter password, but does not accept my password.
2. When I get into F12, boot manager, I can see my USB stick with Tinycore linux but when I select it and press enter, cursor is moving back to internal boot manager. I called Lenovo and Microsoft, both want me to do factory install. :-( Please can I try any other ways before I do that as last resort. Thank you very much

Thank you, I will try but I have tried many ways, It is asking me password and when I say boot from USB, it goes back into windows.
2. I have USB with tiny core linux already, Boot manager is showing up the USB but when I select and click enter, selection moves back to boot from ROM.

But I will try with Ubuntu too and I have lenovo USBrecovery, I will try with that.

I am not sure, why command Prompt is being controlled by Windows. Cannot I change the settings which does not let my laptop boot windows at all ?

If there is no password prompt then command line can be used to rollback windows updates.
Command line can be used to modify the misbehaving driver: MFEHIDK.SYS

Sorry but IMO this Feature update is NOT ready for prime time- revert to 1909 or 1903 if you can.
