External dll SEHException ntdll crash

Patient is a C# application compiled using VS 2008. Application runs on multiple client computers using Windows 7 64bit and Windows 10 Pro 64. On June 11 they reported problems with application, probably after some windows update or another application installation, something changed in environment.

Trying go back to VS 2008 and debug situation leads us to System.Runtime.InteropServices.SEHException on line where external delphi library dll is called.

Since then we take multiple tests on client and own computers. But we were unable to create repetitive scenario, turns out sometimes it work sometimes not. We're looking for any hints since after week spend on problem we're not moving forward with this problem.
