If you can show that the year end process was in some way unfair or unreasonable.
If you can show that some of the feedback is not accurate etc.
If you can prove your manager said what you are saying they said.
Then you have a very strong case.
I would try and gather plenty of evidence to dispute the feedback where possible. That is your best bet.
If a colleague was present when your manager made that statement then they should be a witness.
Being put on a PIP can indicate that you are being pushed out (not always). If so, this sounds like constructive dismissal to me.
