VCPs for vSphere 6.0 and 6.5 retired at the end of August.
Take a look at this page: VMware Certified Professional - Data Center Virtualization 2019 (VCP-DCV 2019)
As you're not currently a VCP, you'll need to take a vSphere 6.7 class.
EDIT: As you're already a VCP5-DCV, you just need to pass 1 exam.
