Unhandled exception at 0x7779e6eb in MyApplication.exe.4036.dmp: 0xC0000409: 0xc0000409

Unhandled exception at 0x7779e6eb in MyApplication.exe.4036.dmp: 0xC0000409: 0xc0000409.

I am not sure that Redemption.dll is causing the problem.

We are using Redemption 5.20. the error only happens after we send multiple emails. Sometimes it is 3, sometimes it is more. But, it only happens on machines that have Windows 10 (tried on v. 1903 or 1909) and outlook 365.

The Application works fine in other versions of windows/outlook. There is no capturable error in the application, it justs crashes back to the OS with no error. So, we had it create a dump file.

The dump error is (where RMinisoft.dll is the rebranded redemption.dll (32bit)): Unhandled exception at 0x7779e6eb in MyApplication.exe.4036.dmp: 0xC0000409: 0xc0000409.
