Controlling Client crashes by using too detailed dimensions

Hello

I have a crosstab where I put a Hierarchy for cost elements on one of the axis

The issue is this: I also added a costcenter selection in the head line. I can select cost elements but after the third time I select a new cost center (or cost centers) the Controlling Client crashes (I am using Controlling 2019 build206 (16927)). I made the following observation: if my crosstab has the points open (like this)

I get the Client crash. But if the crosstab looks like this before I change the cost center in my selection bar

I can change the cost centers as often as i want and nothing happens. Can there be issues if I have too much data shwoing when I do new selections? Or is perhaps my hierarchy too detailed (too many subsections)?

Thanks for your help
