This just happened to me. I went through my sequence and looked to see if anything in there was odd. I had used a rather large PSD at one point. I took it out and tried to output. That wrked fine. I went back into PS reduced the image size, put it back where it needed to go in the edit and BOOM. The good “BOOM”. All is now well.
I would check the sequence to see if there are any large image files. If so take them out, reduce their size in PS, reimport and replace. See if that works. I guess you had this problem 2 years ago, but maybe this will help others.
