ASP:NET: ErrorCode = '0x80004005: ff' when publish to IIS

I have a problem with IIS and ASP.NET Core. I've put on my destination server ASP.NET Core version 2.2.0 and the I've put my solution that use the same Core. When I try to browse my Application, this message appears in the browser:

HTTP Error 502.5 - Process Failure

I try to find it in the Event Log and get this message:

Application 'MACHINE/WEBROOT/APPHOST/DEFAULT WEB SITE/DEAFACTOR' with physical root 'C:\inetpub\wwwroot\DeAFactor\' failed to start process with commandline 'dotnet .\AspNetMaker2018.dll', ErrorCode = '0x80004005 : ff.

Looking on internet I saw that the cause could be due to some file missing or not accessible, but my folder has all kinds of permission (not to be wrong).

Can someone help me?

Thanks, Matteo.
