This is my code and I'm using R2021a.
clear all;
[signal,fs] = audioread('sample.wav');
f_d = 0.025;
f_size = f_d*fs;
n = length(signal);
n_f = floor(n/f_size);
temp = 0;
for i = 1 : n_f
frame(i,:) = signal(temp + 1 : temp + f_size); % Warning is showed here;
temp = temp + f_size;
end
if mod(n_f,2) == 1
frame(n_f+1,:) = zeros(size(frame(1,:)));
n_f=n_f+1;
end
save('framed');

Make sure that your variable f_size is an integer, perhaps something like this solves your problem:
f_size = round(f_d*fs);% ceil or floor should also work if you prefer either
