readtable failing on MATLAB documentation example

I am trying to perform a read of a simple CSV file. When my code did not work, I decided to run the exact example provided in the MATLAB documentation. I get the exact same cryptic error message. Otherwise MATLAB seems to be working perfectly.
Matlab example .csv data, I placed in "test.txt" (I also tried with "test.csv")
LastName,Gender,Age,Height,Weight,Smoker
Smith,M,38,71,176,1
Johnson,M,43,69,163,0
Williams,F,38,64,131,0
Jones,F,40,67,133,0
Brown,F,49,64,119,0
commands run after a "clear all"
filename = "test.txt"
T = readtable(filename);
resulting MATLAB error message:
Error using readtable (line 216)
REPLACE: "what" and "by" matrices incompatible
Note: readtable detected the following parameters:
'Delimiter', ',', 'HeaderLines', 0, 'ReadVariableNames', true, 'Format', ''
I traced execution through the MATLAB's readtable.m and subsquent calls and verified that the file is opening, the header line is read, and initially the "guessed format" appears correct. After determining the data format, MATLAB raises an exception at the next higher step in the call hierarchy. I've tried quite a few variations with and without various function options/arguments.
Any idea what I am doing wrong?

Mine shows
>> which -all readtable
C:\Program Files\MATLAB\R2020b\toolbox\matlab\iofun\readtable.m
C:\Program Files\MATLAB\R2020b\toolbox\shared\io\general\+matlab\+io\@ImportOptions\ImportOptions.m % matlab.io.ImportOptions method
Can you upgrade to the newest version? why stay stuck on a 2 year old version?

That's what R2019b shows; R2017b shows the one file; I don't have R2018b installed to check.
OP could also check to see if are updates to the release he has installed.

As Steven L, suggests, show us what
which -all readtable
shows and we still don't know which release you're running, either.
