Since the Word update to version 2405/2406 on May/June, we have different problems with Word.Interop.

We have a VSTO addin developed with c# to interoperate with Word, in which we use the Interop.Word.Document.ContentControlOnExit event to manage behaviors, one of them sets Interop.Range.HighlightColorIndex, this causes a Word crash in these versions, in 2404 it works.

We also have this problem: https://answers.microsoft.com/en-us/msoffice/forum/all/after-installing-word-version-2405-on-may-30-2024/e8e704ea-96ce-4380-bc6a-30e3911c95b5

Does anyone have a workaround for this problem?
