Every so often I need to create a handful of polygons from a csv containing points. Back before we shifted to 3.0, the tool "Coordinate Table to Polygon" in the Defense Tools "Conversion" toolbox used to work A-OK. I'm running Pro 3.0 on a work computer (heavily restricted environment) and have yet to give up and run it on Pro 3.1.3 on my personal machine. Regardless, the tool still throws the following error no matter how many tricks I try to make it work:

I found this community post from someone else who is experiencing the same issue. The only engagement on that post was from me, the last time I tried to use the tool and it wouldn't work, throwing the same error. <argh>
The table is saved as a CSV in UTF-8 format. These are the points (attached below as well):
