Hyper-v and Vmvare still can't open together(Workstation 16 Player and Workstation 16 Pro can together with Hyper-v). Details here (opens new window)

What I did was uninstall Workstation 15 Pro and install Workstation 16 Player on my own windows10.

Still this error. Also, I met another error, the error told me something about counters. So I go to find it. Finally, find counters at Virtual Machine Settings's Hardware's Processors: at the right of Virtualization engine, found Virtualize CPU performance counters. Uncheck it, solve it.

The HV maybe Hyper-v, found Virtualization engine's Virtualize Intel VT-x/EPT or AMD-V/RVI, still uncheck it, solve it.
