I have uploaded the debug log, the pop-up and the expanded pop-up.  The full text of the pop-up is below.

I am the only one using this server.  I could run the debug kernel or test kernels, if that would help.  I spent a few years writing Linux device drivers back in the day, so system troubleshooting isn't new to me.  Plus I feel like I have been alpha testing Windows 10 since it forced itself on me a few years back, so what is one more project?

The text of the pop-up:
