I’ve never seen anything like this before, I just learned it’s called an ice heave. In the video you can see how the fall over like dominoes

Never knew what it was called, thanks!

Frost heave is swollen soil.
Aren't these frost flowers?

Looks like they are actually needle ice

Wow, I am learning two new things about frost! And I'm from Greenland lol.

I think this is deposition; a phase change (condensation, evaporation, etc.) where the cold morning air skips the liquid moisture phase and directly becomes a solid, the frost.

No, pretty sure the Heave thing is correct, especially since it can essentially be ‘underground’ when muddy soil freezes hard and pushed the water content upward as ice.
I come across it all the time here in the NE, on winter hikes mostly, especially on a cold (20° or below) morning when the previous day was warmer/rainy.

I've seen this happen before, always so cool to come across.
