Probably a duplicate (or similar root cause) of the other bug you are working on.

I've looked at this a little bit already and summarized my findings so far in bug 1985998. The bottom line is that this crash will occur any time you try to decompile an MSI that uses a different schema for the RadioButton table than the one in WiX's tables.xml file.
There was a recent fix for bug 1903337 that changed the length of the text field in the RadioButton table, and that causes some MSIs that previously decompiled correctly to no longer work. However, it also causes other MSIs (such as orca.msi) that previously would crash with this same call stack to start decompiling correctly.
