Stop the AppPool and the website also. Delete content of the bin folder of the plugin (hosted folder's location==>Plugins==>bin) or the bin folder itself then start the AppPool first and then website. Seems shadow copy related issue.

If possible share the details error. To get details error open the webconfig file then set stdoutLogEnabled=true.

I download source code and publish Nop.Web by VS 2019.
I add some configs for run with IIS.
