Hi Rami20 ,

Even with the April update, this issue can still occur because it is environment dependent rather than strictly tied to the Power BI Desktop version. Please check the version of Newtonsoft.Json in the GAC at C:\Windows\Microsoft.NET\assembly\GAC_MSIL\Newtonsoft.Json. If it is 13.0.1, the issue will persist, whereas 13.0.3 or higher should resolve it. Power BI (March/April) requires Newtonsoft.Json ≥ 13.0.2, but if an older version exists in the GAC, it overrides the bundled version, causing .pbip files to fail. As a temporary workaround, you can try using the January version.

Hope this helps.
