Hello, I'm trying to update Windows 10 Professional from 1909 to 20H2. Unfortunately, it repeatedly fails. Error Code is 0xC1900101 0x30018. I upgraded the system from Windows 7 to Windows 10 last December. This worked fine; since then, no hardware has been changed. I've checked my drivers for updates and am running the system with only few programs. It is a sole gaming machine. I've run SetupDiag which created an empty text file.
Here, you can find setupact and setuperr from the panther-folder and drivers.txt: https://www.dropbox.com/sh/os9si3r1o21w0x7/AACBPGpo-PhtTNHx0jsKwgv9a?dl=0.
Do you have an idea what could cause the problem?
