http 502.5 process failure error

I have recently purchased vps windows 2016 server from godaddy with plesk control panel.
when I create a site using plesk and tryies to access it, it gives me error HTTP Error 502.5 - Process Failure.

I have installed almost every core version suggested.
Given full access to application pool user.
enables stdoutLogEnabled to true, but it is creating empty log file.

the site published directly to wwwroot folder of inetpub is working fine.
but those which are under plesk are not working.

<aspNetCore requestTimeout="23:00:00" processPath="C:\Program Files\dotnet\dotnet.exe"
arguments=".\Nop.Web.dll" forwardWindowsAuthToken="true" stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout" startupTimeLimit="3600">
