I’ve put in a dispute with PayPal just waiting for something back

Hopefully they don't use tracking to decline the claim.

If PayPal reject the claim can I still go to my bank provider and charge back?

Yes you can, but given your bank will collect all details about your claim, It's likely they'll see that It was declined by PayPal and they may do the same based on PayPal's decision.

And also I forgot to mention that if PayPal takes apples side, I paid with a debit card so I wouldn’t be protected under section 75

That Is correct.
