System.Runtime.Serialization issue on starting PowerBI

[neebong]

Hi,

Getting this error on running PowerBI, everything has been working normally until recently.. Unsure if it was a Windows Update or PowerBI Desktop update as they were both done around the same time.

Anyone have any ideas?

Hi  @neebong ,

Have you ever tried clear the cache in Power BI Desktop or install the latest version ?

Best regards.
