I have sent you an email with a debug version of WinSCP to the address you have used to register on this forum.

I've tried the latest version and still WinSCP process is crashing and giving the same exception.

I can not find solution yet

I've developed a .NET console application to run as a WebJob under Azure App Service.

This console app is using WinSCP to transfer files from App Service Filesystem to an on-prem FTP Server.

It's perfectly working on Development & Testing. But when deployed on Production, we got the below error:

WinSCP process terminated with exit code -1073741819 (C0000005). There was no output. Response log file D:\local\Temp\wscp550C.03E988EE.tmp was not created. This could indicate lack of write permissions to the log folder or problems starting WinSCP itself.

Any clues?
