Please follow @JMH's excellent list of things to try. If you *still* have a problem, please:
Copy the C:\Windows\Logs\CBS folder to your Desktop, right click on it > Send to > Compressed (zipped) folder, and upload the new file which is created on your Desktop here.
Thanks a lot!
P.S. It is important to try @JMH's list first, because tools like the System Update Readiness Tool create log files, as does SFC, and so collect logs after running these, so that I can analyse those logs as well
