Ok, your first crash log shows that you have some serious network issues. Either you're on crappy WiFi that is dropping packets like crazy, or you did not exclude the client and save folders from security software. I cover the former
here, and the latter in detail
here. You do not crash the client, and it does exit normally.
Your friends first log looks just fine except that it ends without any error or crash dump. This indicates that the crash occurred externally. When it happens to him again, I would suggest checking the Windows Event Viewer for messages. It may be caused by a compatibility issue with some other software, or security software terminating the task.
Their second log is basically the same story.
On a final note.... Between the two of you, your friend has a much better CPU for hosting than you do. That laptop is going to struggle with the basics, and their desktop chip has considerably better performance.
