I noticed the strange bug.
If I use the Nop 4.60.3 with the .NET 7.0.1
https://dotnet.microsoft.com/en-us/download/dotnet/thank-you/runtime-aspnetcore-7.0.1-windows-x64-installer
from this page
https://docs.nopcommerce.com/en/installation-and-upgrading/technology-and-system-requirements.html
I saw a lot of errors in nop logs (like this error)
System.IO.FileNotFoundException: Could not load file or assembly 'System.Net.WebHeaderCollection, Version=7.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The system cannot find the file specified.
File name: 'System.Net.WebHeaderCollection, Version=7.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'
I installed the new version
https://dotnet.microsoft.com/en-us/download/dotnet/thank-you/runtime-aspnetcore-7.0.5-windows-x64-installer
but I think we could use the version 7.0.3
