If you haven't already, try having a look at some of the background applications/drivers which are known to cause issues if they are running while playing
Amnesia. They can be found
in the Troubleshooting Guide under Problem A4.
The hpl.log states you're using an nVidia graphics processor as well -- Do you perhaps have
nVidia GeForce Experience or an external application similar which may be altering
Amnesia's graphical settings? If that's the case, maybe toy around with some of the settings or disable it altogether for
Amnesia in case it is causing some inconsistencies.
A new log could also help pinpoint things if the crash has become something else entirely (since now, as you said, it now crashes at the start).
