Problems with "there's not enough memory to complete this operation."

[Kikihoffman]

Hi,

I have a 516KB report with quite a lot of measures and calculated columns wihch have been working perfectly fine until this Monday.

Out of a sudden it stays "there's not enough memory to complete this operation." no matter what I try to do. Even delete any measures or columns which I think could be a problem.

Whenever I open the report it also says: "Unable to execute DAX - there's not enough memory to complete the operation". 

However, I am not able to see which DAX is actually causing the problem.

I have tried this tip: Power BI Performance Issues and memory consumption (designmind.com) without any success as well as reinstalling PowerBi

I have attached a picture of the Task Manager while trying to delete a simple measure before it finally fails..
