There is artifacts in baking high count of probes, i can see them in the video, any way to get rid of them?

There's always artifacts in my experience, regardless of bake settings. Thankfully for a project like this such artifacts are generally hidden by the low lighting and gritty textures. One thing you can try is the Irradiance Smoothing setting in the Indirect lighting (Eevee render properties):

This setting blurs the irradiance bake which tends to darken the bake overall but also reduces the obviousness of the artifacts.
