What is this on my O2 sensor?

I recently changed my O2 sensors and after that my car would go into limp mode after exceeding 3k rpm. I discovered that fuse four in the dme fuse box was blown which caused me to look at my O2 sensor. After cleaning it out and replacing the fuse the car runs with no problems but I don't know why the O2 sensor had that problem in the first place. Does anyone have any idea what it might be? The O2 sensor is a Walker SKU 350-34178.

That would be hilarious if they put antiseize on the wrong side of the sensor.

Edit: Almost looks like LiquiMoly bearing paste

My first reaction was exactly that when I saw it but I thought that wouldn't make any sense. I guess they were just a little brainless installing it lol
