While the error presented is remarkably void of content, what would help the person debugging the problem is a series of steps that allow them to duplicate the error. So if you can repeat what you did when the error occurred, record those steps and the problem will be fixed much sooner. Until one can duplicate an error, it is very hard to fix it. Bury them with data. They will be happy, not angry. I promise. Difficult to get into a TMI situation when debugging.
Before being a retired software engineer, I spent many hours trying to duplicate a problem reported by users. Besides you need a reproducible error to test the fix you put into the software to see if it was resolved.
From a dweeb happy that someone else has to fix it.
