RedHat CodeReady Container command: crc start -p .\pull-secret.txt execute failed - containers

Question

I'm trying to setup CodeReady Container on my company laptop following RedHat document, but I got below error when I executed crc start -p .\pull-secret.txt command:
PS C:\lab\RedHatCRC> crc start -p .\pull-secret.txt

Your system is correctly setup for using CodeReady Containers, you can now run 'crc start' to start the OpenShift cluster
Then I checked the vmswitch on my laptop:
PS C:\lab\RedHatCRC> Get-VMSwitch
Name SwitchType NetAdapterInterfaceDescription
---- ---------- ------------------------------
Default Switch Internal
Yes, there is no crc vmswitch. But there is no any hint from RedHat CodeReady document. Could someone help here?
Thanks in advance!
