UE4 Crashes everytime at startup after trying to record movie using Matinee

Hi ,

Like many I have been experiencing this problem. Creating an AVI movie in matinee worked until recently. I am currently using version 4.9.1. I’ve added a few particles to my scene since it worked last. Now it just crashes every single time. I have deleted all the old files in my “Video Captures” Folder, and restarted to no avail. I have attached my crash report and what it reveals every time, not sure what to do next. Any help would be great getting me on the right track with this issue

Thank you,
