I have experienced the same problem. I also notice that when the game freezes, the background music still plays on. But sounds of animals (goat farms etc.) stop.
I have a world of appr. 75 Mb. When I am in an area with a loth of farms (cow, sugarcane, melon, pumpkin etc.) I experience more lags and they last longer. In an area with no farms there are very few lags.
Since the update 1.18.31 I can play the game for about 30secondes. After that it freezes for 45 secondes. Than I can play for 5 secondes and the game freezes up again.
