AutoEQ block makes sigmastudio slow and not responding

Hello, I use AutoEQ 2-way block in sigma studio. It makes Sigma studio extremly slow, not responsive and in task manager its marked as "Not responding". Calculation of filters takes about 30 minutes, changing gain of tweeter another 10 minutes, saving the project 1 minute. These are all the times that sigmastudio appears as not responding, even mouse cursor is not showing. After that time, everything works fine until I want to modify some parameter, then I wait again. In the end, I made a successful working project, but it took a lot of time. The project is attached

Computer spec

Core i7 3.4GHz, 16GB RAM, SSD, Windows 10 home

Also tried on 2 laptops, both i5, 2.5 and 3GHz, 8GB RAM - behavior was the same
