simple readtable() call throws error

Trying to run a one line script containing:
data = readtable("data.txt");
Where "data.txt" is in the same directory and contains:
0, 1
100, 2
200, 3
300, 4
400, 5
And I get the error:
Error using readtable
Dimensions of arrays being concatenated are not consistent.
Error in readtabletest (line 1)
data = readtable("data.txt");
What arrays are being concatenated??
I have tried changing the delimeter to spaces too

Works fine for me here -
data = readtable("data.txt")
data = 5×2 table
Var1 Var2 ____ ____ 0 1 100 2 200 3 300 4 400 5
Can you upload your "data.txt" file so we can reproduce the error?
However, I have the error no matter what file I use
It worked fine with me too.
What MATLAB version do you use?
See Release in the right margin of this page.
Pleaes share the result of the following code
which readtable -all
which readtable -all
outputs:
E:\Program Files\MATLAB\R2022b\toolbox\matlab\iofun\readtable.m

1st of all, verify and make sure that if you're calling the correct file. You may have two different files with the same name but different contents in two different directories
Here are four different ways to read data from data.txt:
D1 = readtable('data.txt')
D1 = 5×2 table
Var1 Var2 ____ ____ 0 1 100 2 200 3 300 4 400 5
D2 = readmatrix('data.txt')
D2 = 5×2
0 1 100 2 200 3 300 4 400 5
D3 = importdata('data.txt')
D3 = 5×2
0 1 100 2 200 3 300 4 400 5
D4 = dlmread('data.txt') % Not recommended
D4 = 5×2
0 1 100 2 200 3 300 4 400 5
