OpenXML adding images to a Word document randomly corrupts the file

Question

After adding one or more images to a Word document, I try to open it using Word Interop. At random, the document is corrupted and will throw a COMException "the file may be corrupted".

While trying to determine a cause for this corruption, I used the same document, images, ... over and over again. When my application starts, there's about 70% chance that it will open without issues. Then it will continue to regenerate and open just fine, until one random point after a few attempts where I'd get that COMException. After that, it will continue to throw that exception until I restart the application.

The corrupted document and the one that opens show no differences in the generated XML, apart from the ID's that are generated for the images.

• .NET Target: .NET Framework 4.6.1
• DocumentFormat.OpenXml Version: 2.11.3

The code to add the image:

        var element = new Drawing
        (
            new DW.Anchor
            (
                simPos,
                horPos,
                verPos,
                new DW.Extent() { Cx = dimensions.ImageWidth, Cy = dimensions.ImageHeight },
                new DW.EffectExtent() { LeftEdge = 0L, TopEdge = 0L, RightEdge = 0L, BottomEdge = 0L },
                wrapper,
                new DW.DocProperties() { Id = (X.UInt32Value)ticks, Name = $"Picture {ticks}" },
                new DW.NonVisualGraphicFrameDrawingProperties(new A.GraphicFrameLocks() { NoChangeAspect = true }),
                new A.Graphic
                (
                    new A.GraphicData
                    (
                        new PIC.Picture
                        (
                            new PIC.NonVisualPictureProperties
                            (
                                new PIC.NonVisualDrawingProperties() { Id = (X.UInt32Value)ticks, Name = $"New Bitmap Image {ticks}.jpg" },
                                new PIC.NonVisualPictureDrawingProperties()
                            ),
                            new PIC.BlipFill
                            (
                                new A.Blip(new A.BlipExtensionList(new A.BlipExtension { Uri = "{28A0092B-C50C-407E-A947-70E740481C1C}" }))
                                {
                                    Embed = relationshipId,
                                    CompressionState = A.BlipCompressionValues.None,
                                },
                                new A.Stretch(new A.FillRectangle())
                            ),
                            new PIC.ShapeProperties
                            (
                                new A.Transform2D
                                (
                                    new A.Offset() { X = 0L, Y = 0L },
                                    new A.Extents() { Cx = dimensions.ImageWidth, Cy = dimensions.ImageHeight }
                                ),
                                new A.PresetGeometry(new A.AdjustValueList()) { Preset = A.ShapeTypeValues.Rectangle }
                            )
                        )
                    )
                    { Uri = "http://schemas.openxmlformats.org/drawingml/2006/picture" }
                )
            )
            {
                SimplePos = X.BooleanValue.FromBoolean(false),
                BehindDoc = X.BooleanValue.FromBoolean(true),
                LayoutInCell = X.BooleanValue.FromBoolean(true),
                AllowOverlap = X.BooleanValue.FromBoolean(true),
                Locked = X.BooleanValue.FromBoolean(false),
                RelativeHeight = 500U,
                DistanceFromBottom = 0U,
                DistanceFromLeft = 114300U,
                DistanceFromRight = 114300U,
                DistanceFromTop = 0U
            }
        );

The generated XML for the image is as follows:

If the file opens 5 times, I'd think there'd be no issue the 6th time too right? I'm completely lost as to why this would cause corrupted files at random.
