Where did you installed this version of nopCommerce?
Can you make sure that you are using latest version of MS-SQL, have enough RAM on your system and your system have enough processing power?
Ideally when you run nopCommerce 4.60 with no source or source code version, I prefer to have a system with minimum below configuration: RAM: 8 GB Processor: 2 Core intel i3 or higher Storage: NvME is preffered, not even SSD.
This is not just about nopCommerce but to run any dotnet based application since you also have MS-SQL server.
