The project solved with a Continuous Foundation is not solved on the raft...

There is a project that I'm constantly solving 80 to 80 with Basic. The customer requested a Raft foundation. It gives an error when I try to solve it with raft. No matter how much I increased the thickness, I could not fix the error. Help please...

Continuous foundation data entry is incorrect. The joint points of the continuous foundations must coincide with the column object and be connected to the panels at the nodal points. *Soil safety stress value was entered as a very small value such as 2.2 tf/m2. I think it would be 22 tf/m2. *1. Since there are no perimeter curtains on the basement floor, it would be appropriate to enter the "upper rigid basement floor number" as -2 in the analysis settings. When the situations are corrected in the project, there is no problem when the foundation system is designed as a raft foundation without beams, as in the attached example.
 
I examined your project a bit and found mistakes 1) Your basement is not surrounded by curtains, but you accepted it as rigid? 2) As I understand, there are closed overhangs but there is no wall load in beams with closed overhangs? 3) Although your system is a hollow block, is your coating load low? 4) your typical beam definitions are wrong 5) your beam connections may be healthier. You need to examine your project a little more healthily in terms of studs.

The constant basic data entry in your project is incorrect. The nodal points of the continuous foundations should coincide with the column object and be connected to the panels at the nodes. (Looking at the continuous foundation Reinforced Concrete dialog, it can be seen that all stresses are calculated as zero.) Apart from this; *The elevation of the P01 panel is incorrect. -80 cm of elevation is entered on each floor. *Soil safety stress value is entered as very small as 2.2 tf/m2. I think it would be 22 tf/m2. *As there are no perimeter curtains on the 1st basement floor, it would be appropriate to enter the "upper rigid basement floor number" -2 in the analysis settings. When the above-mentioned conditions are corrected in the project, there is no problem when the foundation system is designed as raft foundation without beams, as in the attached example. Good work
Yes, I didn't notice all the mistakes you mentioned. You are very careful, thank you very much...
