I am using Google chrome and I got the same result as you, it seems to be stuck on that picture. I checked other unknown observations and they at least always seem to provide some ID suggestion, but not this one.
Curiously you get the same result of you look at it in the ID modal. As soon as you narrow the taxon range to e.g. plants or insects you get the normal expected results.
With the existing ID, the range of taxa to be searched has now been limited, and that has worked before too. If you use the ID modal and clear the Taxon filter, it stalls again.
