WV Trooper Walks in House and Demands to be Sued

This morning I received multiple links and copies of this video that’s been circulating, showing a West Virginia State Trooper, in what appears to be inside a family’s home without a warrant. Apparently it was originally posted to Tik Tok, and then removed for some reason. It appears to involve a police response to a church traffic cone, which resulted in the homeowner apparently banging on the church’s door at some point. This trooper shows up, walks in the guy’s home, admittedly without a warrant, and without permission. Then the trooper makes a move on the phone, followed by some sort of altercation at the end. Here’s the video, then I’ll address some legal issues which I see.

Is a warrant required? If not, is there an applicable exception?
