Game breaking bugs

Hi I recently completed the pagani Zonda cinque pursuit legends special event and the game never unlocked the replay able events in the campaign.when I go to garage and click on find more BP, the game bugs out and it's say "long car name car name BP".it does not allow me to exit the garage, I have won the event fair and square and reported this issue on multiple social media but no luck as yet.i cannot get any more bps for the pagani Zonda cinque although Its says I completed it and the replay races is still locked...
