Assembly dependencies missing when publishing Nop 4.20

Hello all:

I have upgraded my site to Nop 4.20 (from 3.80) and have all the files extracted properly and published on my hosting server (Smarterasp). Please note that I am using the no-source package.

However, I am getting the following message:
An assembly specified in the application dependencies manifest (Nop.Web.deps.json) was not found:
package: 'runtime.win-x64.Microsoft.NETCore.App', version: '2.2.3'
path: 'runtimes/win-x64/lib/netcoreapp2.2/Microsoft.CSharp.dll'

As a result, my website is currently not running.

Can someone assist? I have also sent the same feedback to my hosting provider, in case the issue is at their end but am desperately wanting to fix the issue asap.

Thanks all!

Issue being resolved with hosting provider. Thanks!
