Hello BalanujHazarika-1734,
Thanks for your response.
It seems that you have already installed the feature update. The Windows 10 2004 OS Build version as the same in my environment. Here is my environment for your reference:
I found out many articles said that the error code 0X1900101 means a driver crashed when we loaded it for the first time. Any driver could cause the failure, but it may not crash 100 percent of the time. If we try again, it may just work. So it is recommended to wait for a while and observe whether this issue will exist or not.
In addition, this issue is more related to the OS. It is recommended to reopen a case and post this issue on the Windows 10 forum. In the WSUS, we can only support the Release Preview Channel.
Thanks for your understanding and patience. Hope you have a nice day.
Regards,
Rita
