Windows 10 20H2 Monthly Updates fail

[deleted03312021]

Windows Education 20H2, monthly updates keep failing for some months now with error 0xe0000100. Tried the classical sfc /scannow and the DISM restoreHealth commands, which both fail: the sfc fails at 95% verification, and DISM at about 55%. Seems that the CBS.log has a helpful SysReadFile error for a file within the WinSXS folder (specifically: Windows\WinSxS\x86_microsoft-windows-o..namespace-downlevel_31bf3856ad364e35_10.0.19041.1_none_9aef94c8692c24e6\api-ms-win-shcore-stream-l1-1-0.dll), but SFCFix for some reason crashes unexpectedly and I didn't want to change that file on my own with another installation's that I have, may be dangerous and I have also Ubuntu installed on the last partition of the same SSD drive that Windows is installed, so I clearly don't want any harm to be done to my Ubuntu partition. I have submitted the crash and here is its log, and the CBS.zip is attached:

Hi, is there anyone that could guide me to find out what's going on here? It has been quite a long time now... Thanks in advance!

Solved this issue with the assistance of a member here. For anyone interested, the issue were 2 driver files (.inf) within the Windows\WinSXS structure that had somehow become corrupt, and were zero-filled instead of having actual content. SFCFix helped me in this way, at last.
