Been using Calibre for many years and routinely update both Calibre and Windows 10.
After a recent MS update I noticed Calibre did not restart. Tried to restart both the x86 and x64 versions but both act the same way. Calibre starts, I can see the window for about 5 seconds and then it just shuts down.
Here is my calibre-debug /g log:

I was running version 4.21 when this happened so I downloaded 4.22 but the same results.
Thanks
