Hello @basu_P !
Welcome to Microsoft QnA!
It seems that there are some resources into that resource group that were marked for Move Operation
First suggestion is to follow the message
Can you provide details on the actions you took ?
Does the Azure Mover has these resources ?
Verify you can delee them from moving and you will be fine once they are gone from Azure Mover
I hope this helps!
