Receiving strange error for first time

Hi, I have been using unity for about 2 months now, and I am fairly new to programming. I came across then error for the first time when building,

value.byteStart + value.byteSize <= dataFileEnd

Invalid serialized file header. File: “”.

I did some googling and cannot find a specific answer. If anyone can walk me through on how to fix this, that would be great. Thank you!

I figured it out, I had an animation that was causing the problem.
