Dispose Method Crashes Entire Console App

[jason.chase@comtrac.com.au]

We have a using statement that crashes the entire dotnet core console app when the Dispose method is called on the Spire.Xls.Core.SpreadSheet.XlsWorkbook class. The method is wrapped in a try/catch, but this ignored as it takes down the entire process.

This is what's written to the event log:

Faulting application name: phoenix.exe, version: 1.0.0.0, time stamp: 0x5ee99cfc
Faulting module name: unknown, version: 0.0.0.0, time stamp: 0x00000000

I've created a crash dump file and analysed it with windbg. The crash dump proves the Dispose() method is what's crashing the CLR:

This dump file has an exception of interest stored in it.
The stored exception information can be accessed via .ecxr.

And here's the thread's stack that blew it up:

Can you please advise on a way forward with this, as it looks like the Dispose method is using a null reference, however it's taking down the whole CLR app with this native code error:

ERROR_CODE: (NTSTATUS) 0xc0000005 - The instruction at 0x%p referenced memory at 0x%p. The memory could not be %s.
