Jittery GIF - AI to PS Animation

[JM98A7]

Hello, I'm trying to make a GIF in Photoshop using frames exported from Illustrator artboards. The issue is when I animate the frames in Photoshop, the whole image jitters (right to left) by a pixel or two each frame. I double checked that all my artboards are the same size (125px X 125px), and that the non-moving parts of my animation layer perfectly on top of one another. My workaround has been to increase the size and resolution of the artboards so the jitter is less noticable, although still there. Does anyone know how to make this jitter dissapear?

Current workflow: AI > PNG (Export for Screens) > PS > GIF (Save for Web)
