Think on the feedback received in a constructuve manner for what it might contain of value but do not let it undermine your confidence. Use it to get better.

Many of us will receive undeserved negative feedback at some point in our career. Receiving at the start of it, it is just harder to take it but use it to grow. This is one more thing to learn.

I must say that your managers seems pretty rubbish for many things: conducting this meeting wihtout your manager in the room, unloading his fustrations on you and apparent lack of steering.

Whether to leave or not: do not fight it as they are part and judge so you will not win. But have an open conversation what this means. Do not overreact but do not ignore it neither. And be cool, your present job have great things on it but there are many others.
