Consistent JavaScript Error

I'm trying to export my animation from Animate as a video (File>Export>Export Video/Media). However I am consistently met with this same JavaScript Error. I have tried turning both on and off "Render through Adobe Media Encoder" and it has still not worked. I have no extra/third party programs installed, and in fact this is my first time exporting a video on this computer, so I have no clue what could be causing this. Does anyone have any sort of advice or solutions to this? Any help would be greatly appreciated.
