Converting any DWG fails with "The file is corrupt or damaged." in .NET

GroupDocs.Conversion Product Family

Hi, somehow it looks like DWG conversion has stopped working since GroupDocs.Conversion 23.4.
With version 23.3 it was all working and now I seem unable to convert any file to any other format.
I’m always getting the following error:
Cannot convert. The file is corrupt or damaged. Image loading failed: The type initializer for '#=zj78G_2a_Im7q6BQMJ3RyAlIBQ$H1YCfTNg==' threw an exception.

Please see the attached project and DWG files.
Upgrading the NuGet package to any other version did not help either, only downgrading to 23.3.

Hi, I wanted to test this fix, but I somehow can no longer combine GroupDocs.Conversion and GroupDocs.Viewer in the same project.
As I can see, there is no GroupDocs.Total available with that version, so I guess I have to wait for a compatible version of GroupDocs.Viewer to be released?

Currently I get this error when I try to use GroupDocs.Viewer to convert a DWG:

System.TypeLoadException: 'Could not load type ‘Aspose.CAD.InterruptionToken’ from assembly 'Aspose.CAD, Version=23.7.0.0, Culture=neutral,

Is there maybe any workaround for it?
Is there any GroupDocs.Total release planned for this month?

As workaround we would suggest to install Aspose.CAD 22.7 as reference. Seems binding redirects are not helping in the current case. However, after installing Aspose.CAD as reference, it seems to be working for both Viewer and Conversion.
Please find the modified.zip (114.4 KB) project attached. Let us know if there’s any issue.

Thanks for the suggestion.
Unfortunately this does not really work.
It does work if you’re using GroupDocs.Viewer first, but fails when GroupDocs.Conversion was used first.
It’s throwing the error initially reported in this thread.

Hi, I wanted to upgrade GroupDocs, to test a few of the many fixes you have created since the last upgrade, but it seems like this is still preventing me from upgrading :frowning:

I’ve used 24.2 for both, GroupDocs.Viewer and GroupDocs.Conversion.
They are both used in GroupDocs.Total too and are both using the same Aspose.CAD.dll 24.1,
but I’m still seeing “CorruptOrDamagedFileException”

GroupDocs.Conversion.Exceptions.CorruptOrDamagedFileException
