I recently created an animation with 4 particle systems and some force fields. It starts out correctly, but at ~frame 60 one of the particle systems starts glitching like this:
Frame 65 enter image description here Frame 66 enter image description here Frame 67 enter image description here Later this happened to the blue and white particle systems as well. I have attached the full 630 frame animation and the blend file. Sorry that it is in the video sequencer screen.

I can't reproduce your issue ... so I would say for two reasons

  • Enable Output Properties > Output > Image Sequence > Overwrite
  • or try under Particles Properties > Cache > Delete All Bakes and Bake All Dynamics again

  • $\begingroup$ It's not the image sequence that is giving the error, as it is showing up during the render process as well... As for baking, Is there a way to bake all 4 particle systems at once? but thanks anyways. $\endgroup$ Feb 24, 2021 at 16:38
  • $\begingroup$ Since Ovewrite was disabled there could be chance there left some old images, but OK. For Bake - that is what I wrote "Bake All Dynamic" button bakes all at once. I suggested delete all bakes since there could left also some mismatch. $\endgroup$

  • $\begingroup$ I have deleted all previous images from the render folder. As for the "Bake all Dynamics,", thanks, I didn't know this existed. Do you know any ways to approximate the size of the bake if I bake it onto my drive? I don't want it to take up system memory. $\endgroup$ Feb 24, 2021 at 16:46
  • $\begingroup$ I'm not sure if I understood ... if you want to save cache on disk enable "Disk Cache" it will create folder in a file directory ... if you are asking how to make saved files smaller use Compression (Light/Heavy) bellow ... or what are you asking for? $\endgroup$

  • $\begingroup$ I was just worried that Bake All Dynamics could only save to memory... That wouldn't go well for me... $\endgroup$ Feb 25, 2021 at 12:00
