In your project, the problematic node and its coordinates are given in the analysis status window. Looking at these coordinates, there is a piece of beam at the junction of the K113-K114-K34 beams with their names on the 1st floor. If this beam segment is deleted, the analysis is complete. Also in the project; * Floor edge is entered under the K20-K35 beams in 5-floor. *From the properties of K113-K114-K4-K25 beams on which D125-D126-D127-D4-D19 console floors sit, -This beam bears the console floor- option should be selected. Good work
