Hi! I have searched quite a lot and I cannot find the cause of this issue.

The grains randomly explode in all resolutions and I do not know why

Some setting details:
-I turned off most constraints, that's why the edges bleed
-10 substeps and 100 iterations
-It's an imported abc walk cycle which I added as a deforming object
-I imported an fbx to fetch a render camera from Maya

Hope somebody can help, thank you.

is the geometry being interpolated properly between frames?
If there isn't any interframe interpolation then the geometry will jump instantaneously from
one position to another. This might cause things to look wacky.

you can check if things are being interpolated properly by going into the global animation settings and
turning off integer frame values (remember to turn it back on after you are done)
