The animation makes curious.  There appears to be a straight line on the NW side of the water area, whereas the north east and east south sides show a jagged pattern.   What is the theory of the straight line?

The water current in Kane Basin and Smith Sound is stronger on the Canadian side.  (On the Greenland side, there is some north-bound current).  I think, therefore, water (and abrasive ice chunks) scour the west side of Nares Strait.  The fast ice on the 'chunky' north and east sides breaks where it may, often between and around frozen-in floes, and nothing challenges its ruggedness.
Arctic ice is healthy for children and other living things.

And in addition to what Tor has just said, the fast ice on the Canadian side gets some much needed shelter in the lee of the two promontories (marked). Bearing in mind that the current is moving NE to SW on that side. Moving quite fast too. Look at today's image and see how far the chunk has moved down the strait.

The original arch to the north is visible too in this image.

After 21 March, there has been very little movement at all right up through the Nares Strait north of the arch and in the Lincoln Sea.

The attached GIF of the Lincoln Sea runs through from March 21 to March 26.

Arctic sea ice becoming a spring hazard for North Atlantic ships

Suggests that the arches in Nares and the Garlic Press are not holding over the winter.
