Eating problem

Is any body experiencing problem with solids? My baby will be 9 month old on 26 and he doesn’t eat anything. I am so frustrated I tried giving finger food like breads, but he won’t put anything in hi mouth and if I put small pieces of kids biscuits or cheese in his mouth he will gag and eventually end up throwing up. I am even trying giving him blended food like shakes or rice cereal lentils but he is not swallowing them either. And if I forcefully feed him purred food most of the time he vomits that food immediately. I give him 80-90 ml puréed food and he is going to be 9 mnths and still I am not able to give him 2 solids feeding a day. Has anybody experienced such disinterested baby in eating. Sorry for long post but I am so frustrated depressed thinking he is not getting any nutrition when he needs tnem💔.
