This is due to when we run PowerCLI it try to execute initialize-powerCLIEnvironment.PS1 kept under %program files%\VMware\Infrastructure\vSphere Powercli\Scripts but it fails due to by default powershell scripts PS1 cannot be executed and it is blocked, I can confirm this by running command Get-ExecutionPolicy and I get result as Restricted. Due to this Powercli vmware related commands cannot be executed and you see error. (I am running one of the Get-VM vmware command)
get-vm : The term 'get-vm' is not recognized as the name of a cmdlet, function, script file, or operable program.
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

To resolve this open Powershell - Run as administrator and execute below command and type Yes to enable script file execution.
Set-ExecutionPolicy Unrestricted
Next just relaunch Powercli and PowerCLI command environment will be available. and you can use connect-viserver to login into vcenter or Esxi host.
