What worked for me was the following:
1- Reducing formula ranges. Example: I had an Index/Match combination where my ranges where set to 1000. I reduced them depending on my number of lines. If the lines with data where 500, I would reduce the range of my formula from 1000 to 510. For those lines that were around 1000 I would kept the range the same.
2-Restarted my computer. Sometimes the error would prompt up and sometimes it wouldn't after restarting.
The third solution is what has caused me null problems:
3-Simply click on the canvas and then export. I noticed that if I was placed in a cell in excel it would cause me the error.
Best,
