Manager's Toxic Behaviour & resignation & early release & NP & Salary

I raised voice against all this, so manager complained this to HR and involved them, and created a negative image of me in front of the senior leadership and HR. He stopped approving my timesheets and still, my timesheets for around 1.5 month not yet approved, which means I will not be getting salary for this time period, although I worked. After all this, HR is just ignoring my emails and not talking anything about my release or last working date, despite my multiple follow-ups. Advice Please.
