No endpoint listening at net.pipe://localhost/UiPath/service/duplex/agent/ that could accept the message

Hello All,
I installed UiPath Community 19.7.0 free addition, but I am getting this no endpoint error for a whole day.

I’ve gone through all the questions related to this error and tried almost all solutions that are suggested. Here are the few things I tried:

1. I’ve made sure Net.Pipe Listener Adapter is running
2. Turned on all features under .Net Framework from Turn windows features on/off .
3. My user account(which is not default administrator account) has administrator privileges. Also I have full control over C:\Program Files\WindowsApps
4. I’ve reinstalled several times after clearing from Roaming & Local folder.

Weirdly, I didn’t face any problem in another machine where the account is default administrator account. A note: It ran there without any Ui Robot process.

Here is the detailed error log if any one wants to see:

15:44:10.5562 => [ERROR] [UiPath.Studio.exe] [1] System.ServiceModel.EndpointNotFoundException: There was no endpoint listening at net.pipe://localhost/UiPath/service/duplex/agent/suddin that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.
