It's not unusual now for Windows to restart a program after restarting from a crash or update. I've had it happen several times.
I know you said you don't have it set to start up automatically, but double check your Task Manager and make sure it's not doing it.
Check your Event Viewer to see if you can match an event at about the time of the shutdown.

Yeah, but it didn't "reboot" it did a complete "shutdown" - didn't even try to reboot.
Nothing in Task Manager for StreamFab when I do a startup without manually launching StreamFab.
I didn't see anything odd in the Event Viewer around the two times that this happened.
I've had enough problems with weird reboots/quirks in Windows (not since updating to Win10/64bit though) throughout the years to know that some of these events can never be pinned down as to what caused it.
I don't know that it is a StreamFab issue, it might well be a Windows issue - I did the last cumulative & network updates on 5/11 for Windows 10/64bit and all updates are current.
I have downloaded a lot of files from different services since then without issue - just this one quirk when downloading those two files from Amazon Prime.
It is just so weird that it happened 3 times immediately after the chime/ding in StreamFab that the file was finished or the second time when it finished the second file (then ding) and no more files were set to be processed in StreamFab.
Maybe the two different log files I provided can reveal something, but I'm not holding my breath...
