Sudden Resources Exceeded

Hi,

I suddenly started getting "Resources Exceeded" for my main KPI table. Yestarday everything was just fine, and today it can't even load.

When I check performance analyser I get crazy numbers:

However, when I go to the dax studio everything seems "fine" (This is a switch table with 11 branched measures, so it normally takes a couple of seconds to load)

Individual measures all take less than 100ms to load and have around 20SE Queries.

Does anyone have a suggestion what may be a root cause here?
