Issue with Analytics view on on premises Azure DevOps Server

Dear All,
I am using Azure DevOps Server (on premises) and I'm stucked with following error message:
"Method not found: 'Void System.Data.Entity.Core.Objects.ObjectContextOptions.set_DisableFilterOverProjectionSimplificationForCustomFunctions(Boolean)'."

The error occurs in the two following cases:
1) When trying to open any Analytics view
2) When trying to load DevOps Data in Power BI Desktop

Does anyone has an idea about the root cause and the fix to apply?

Thanks in advance,
Nicolas
