The first two definitely look like they were shot through reinforced glass.
The effect in the first image looks like moiré caused by the coincidence of the pattern of pixels with the pattern of the reinforcement in the shatter proof glass.
The second image shows much less moiré and a clearer image of the reinforcement.
In the third image was either not shot through the glass or the distance from the camera to the glass was significantly different than in the first two.

Had a clear UV filter for protection.

Not shot through anything except air. Shooting from the players bench, no glass, no nothing.

This is nothing like the pincushion effect which is the pinching of the image in the center. It’s a lens distortion— but it looks nothing like this.

Could this be a problem from post editing in LR Classic? I have no idea about this problem. It only happened it seems when I first starting to shoot the game. Shot about 1100 photos and less than 1%
came out like these, at the beginning of the match.

There is a definite moiré pattern in the first image and a weaker one in the second. The regular pattern that is interfering with the sensor pattern covers the entire second image from corner to corner.
So if it's not the glass, maybe its the camera.
The third image was at ISO 3200 and 165mm - no moiré and no pattern.
The first two images were shot at ISO 6400 and 200mm focal length. Maybe that is just not a good combination for your camera.
The only thing left is the Lightroom processing. Since I'm not an Adobe user, I will let someone else comment on that.

Can’t help you with LR. I don’t use it. Good luck!

It appears to me that you have exceeded the limits of the camera/lens for the lighting conditions. I may be off but I have seen this before with a friends Cannon camera, looked just like this.

Note: the “pinching in” of the grid lines over the side of the player’s head is a precise demonstration of the “pincushion” deformation. There are strange peripheral deformations as well, but pincushioning is classically centripetally adaxial, as in this image.
Absent knowledge of the cause of the grid lines renders explanation of central adaxial deformation combined with peripheral abnormalities problematic, but it does suggest that a role of the lens in the phenomenon ought be considered.

So why no pincushioning of the face? Or the other patterns inconsistent to pincushioning off to the left of your lines?
This looks like no example of pincushioning I have seen in any lens test. If you have an example, please post the link

At one point I had an older Fuji S6000fd that sometimes did something like this in cold temperatures. There would be a "grid" and colors were washed out. It came to my mind since you are shooting hockey...
I've had to send it for warranty repair and it helped, but after a while it started doing the same thing again. I don't think I have used that camera ever since or at least not in winter.

The first one is called a moire pattern. Only cause I can think of, as someone else mentioned,
is that you're shooting thru the plastic barrier. That can cause all kinds of distortion. One solution:
get up higher in a bleacher seat so you can shoot over the barrier. The downside, of course, it
that you wan't be at ice level. One other thing you can try as an experiment is to put your lens
right up against the barrier (touching it) and see if this helps. If you're already doing this, try
backing off a little (but not much). Best of luck. >Alan

Since it's worse when you start shooting, it must be related to the camera. Can you reproduce this effect shooting elsewhere? Definitely a strange effect. It would be nice to unravel this mystery.
