Im thinking the glass material is causing these artifacts but I'm not sure and I don't know where to begin to fix. Please assist. I've provided a link to my blend file.
Also a note, It looks great all the way until the very last second of the rendering. I've tried increasing my sample size and light paths. blend file https://drive.google.com/file/d/1ijLczaE_jHWRV4IM7a37v1aZ0QI5S1pZ/view?usp=sharing
