Application crashes as a service but runs without issues manually

I have deployed and nopCommerce v4.60.5 to my Debian 11 server for testing.
When I start the service to handle the application state I get a following error:

root@localhost:/var/www# sudo systemctl status nopCommerce.service
● nopCommerce.service - Example nopCommerce app running on Debian
     Loaded: loaded (/etc/systemd/system/nopCommerce.service; disabled; vendor preset: enabled)

If I manually start the application it runs without issues.
Here is a snippet.

root@localhost:/var/www/nopCommerce# sudo systemctl stop nopCommerce.service
root@localhost:/var/www/nopCommerce# dotnet Nop.Web.dll
info: Microsoft.Hosting.Lifetime[14]
      Now listening on: http://localhost:5000
info: Microsoft.Hosting.Lifetime[0]
      Application started. Press Ctrl+C to shut down.
info: Microsoft.Hosting.Lifetime[0]
      Hosting environment: Production
info: Microsoft.Hosting.Lifetime[0]
      Content root path: /var/www/nopCommerce
info: System.Net.Http.HttpClient.default.LogicalHandler[100]

I verified the permissions, and tried reinstalling service but didn't get anywhere.
Please advise.

Hi, could you tell me the specifications of your RAM server?

Would you post here the content of you /etc/systemd/system/nopCommerce.service file.

Also do this command and post info here.
dotnet --info

Hi. This problem was described earlier and has already been fixed in the minor release 4.60.6. In short, for some reason in some environments, the .net core stopped finding some assemblies, we solved this problem by loading such assemblies ourselves.
