My guess would be water froze in the skimmer and pushed upward against the winter cover. This translated to pushing the skimmer inward.

I can speak from experience that if it didn't cause anything to break or tear to the skimmer or your pool then you aren't in any imminent trouble. I had it happen several years ago and everything is still operating mostly normally. However it is something you will want to keep an eye on, especially if you notice any change in the size or shape of the indentation.

You are looking at a complete collapse about to happen, contact your insurance company, it might be covered but more than likely they will use the snow load excuse.

It looks like one of the kids could have backed into that with the lawn mower... 🤔

That is damage from either ice or too much weight (water) on top of the winter cover. There are creases in the wall from top to bottom.

You may have had a leak or water was displaced out of the pool and the wall buckled under the strain of the cover. When using a solid winter cover it is important to remove as much liquid water off the top of the cover as possible.

Personally I would not consider that wall area safe and would recommend removing most of the water from the pool to reduce the stress on that area to prevent sudden failure of the wall.
