Error converting datetime to month names

I want to convert numbers 1-12 to month names in a text string (January, February, etc...) I was using this:

for m = 1:12
t = datetime(m,m,m)
mon = month(t,'name')
end

and it was working fine, however I tried this same exact thing and now it is no longer working, I am getting this error: Function 'subsindex' is not defined for values of class 'datetime'.

Does anyone know how to fix this, or another way to do this?

Perhaps you are calling from a different directory, finding a local function named month?

What do you get when you type

which month -all

?

In order for that particular error to have occurred, you would have to already have a variable named "month", in which case MATLAB would think you were trying to index that variable using a datetime as the index.
