NS_E_WMP_CONVERT_PLUGIN_UNAVAILABLE_NOERRORURL (0xC00D115D) is returned when the required import/conversion plug-in cannot be loaded and no provider URL can be offered.

Change only one precondition: use a known file owned by the same handler and trace CoCreateInstance plus module loading.
Compare the first nested status and next Player event with the failed run.
After testing it, restore the original configuration if the change was diagnostic only.
