I can’t do a chain stitch, it’s always tight and the hook doesn’t go through, what’s wrong what should i do?

So the yarn I’m using didn’t have it written what size it is I tried using different hook sizes I started with 5.00mm then it didn’t work out I tried most of them from 3.00-6.00mm and I only got it to work out once with the 3.50mm and it was very tight as well I don’t know what I’m doing wrong It goes through with one chain stitch then doesn’t work out with the rest I made sure to check that the knot isn’t too tight on the hook and there is a gap
