clc;
clear;
fileReader = fopen('datafile_5.csv','r');
index = 1;
while ~ (feof(fileReader))
    line = fgets(fileReader);
    tweet_info = struct();
    split_values = strsplit(line, '"');
    
    tweet_info(index).sent = string(split_values(2));
    tweet_info(index).content = string(split_values(12));
    tweet_info
    index = index + 1;
end

MatLab says the error occurs in the line that says tweet_info(index).sent = string(split_values(2));

Look at the variable line. If you're expecting it to have multiple fields (e.g. sent, content) and it doesn't follow the expected format, then you'll have to figure out what the line means conceptually. It might mean that you skip that line, or maybe you'd parse it differently.
