An opportunity to reset a bad reputation

Turning from negative behaviour at work may mean that people will not automatically see you as changed. Instead, they may continue to interpret your behaviour through a certain box they've put you in. As a result, they may be cautious about offering higher-profile projects or leadership opportunities, as the stakes may feel too high.

Speak candidly to your manager about your changed behaviour and see if you can get more opportunities, but moving on might be the only way to really start over.
