Glad you found the issue!

There seems to be other issues with a frozen NURBS cube too
I notice what looks like white vertices showing on the edges

And what looks like a cube inside the cube

Things that seem to help:
Uncheck Double Sided before freezing
Delete floaters

Here's a fix for the freeze nurbs patch

It fixes the bad triangle geometry
Removes floating vertices
Gives option to weld vertices for double sided patches

replace the "freezePatch Double Sided" and the "freezePatch2" nodes inside the NURBSUtilities

I can not see any differences with double side checked or unchecked before freezing
Edit: Oh, I see... Weld Vertices makes it single sided

No, "weld vertices" welds the vertices. It's still double sided. It's easier to see on a plane primitive.
Technically, it actually heals the vertices

Cube on right does not have the Vertices Welded or Healed
Cube on left does
I am still a little confused about what is considered Double Sided

Try it on a plane instead of a cube. It's easier to see. Welding makes the face double sided, 2 faces sharing the same vertices. Not welding gives 2 single sided faces without any shared vertices.

Welding makes the face double sided
Thank you for the explanation
It seems to me that the Question should be changed to better reflect what Yes or No does with regards to Double Sided

So as I understand this process, if the NURBS starts out as Double Sided before freezing, you will get this Question
If it is not Double Sided, you will not get this Question

I do not think that it is important to declare the process "Weld Vertices" or "Heal Vertices"
Any suggestions?
Or..
If the NURBS starts out as Double Sided, it should be converted to Double Sided, without the Question?

I don't have any suggestions for the dialog.

I would rarely be in favor of removing an option and the dialog already defaults to Yes.

I am comparing a tS Plane that is Single Sided to a frozen NURBS Plane that is Single Sided
The tS Plane is invisible on the backside
The frozen NURBS Plane is visible on all sides regardless if you Heal the Vertices or not
