WinSCP.exe crashing in production regularly

I am using 5.1.3 in our production environment.
Approximately every month WinSCP.exe faults and refuses to work via the .NET library or by running the exe.
When I bring up a new login for the production server (new RDP session) the exe works correctly.
So I have to start our software on a new RDP session which causes unwanted downtime.

Following is the dump from event viewer.
Would really appreciate a fix for this one..
