My Swing (PhDPaul)

I have no idea what is going on here. I went out a week and a half ago, shot a 72. Went out last week, same course, same swing, shot a 96. I have no idea what the problem is, but I'm dying here.
Was trying to learn the one-plane swing, but I CANT keep my arms from going above my shoulder plane at the top of the swing for some reason. Therefore, I switched to a version of the two-plane swing and was at least able to make contact.
There are two videos below, a bad one and a worse one. Both are with a 6-iron and the swings were recorded about 30 seconds apart from one another. The bad one goes dead straight with a slight fade. The worse one goes dead to the right about 3 feet off the ground. This is why I shot a 96. I've never hit this shot before, and if someone bet me I could make the ball go this way, I would lose bc I've got no clue. I'll be in your debt forever if you can help. I was doing so well.... hitting a nice draw with plenty of distance....now I feel like I've never played before and I have no idea where whitie might go with the next swing

Bad swing (because I have no idea why it went straight):

Worse swing (don't let your children see this):
