Windows – Power BI – Couldn’t load model schema

microsoft-powerbiwindows 10

I installed Power BI Desktop (win 10 / Product Version: 2.56.5023.1021). The first session was okay, but since the second one, I get the error message "Couldn't load model schema" every time, when I want to open an existed .pbix file. I reinstalled the software several times, but the problem is the same every time. I use the latest release of Power BI. I'm not sure if it is a relevant info but I'm using SQL Server Express 2017 without SSAS.

How could I fix it?

Thank you in advance

This sounds like the same issue as reported here:

The solution posted by Microsoft on is:

Users can work around this issue by running the following command from an elevated command prompt: "C:\Program Files\Windows Defender\MpCmdRun.exe –resetplatform"

Presumably this is some clash with Windows Defender.
