Error creating task: "The given key was not present in the dictionary."

When creating a task from an account (Regarding is pre-populated) I get this error. However, I can create a task independent of a parent record with no issue. I tried to look for any workflows or plugins that might be causing this error, but did not find anything.

"The given key was not present in the dictionary."
