hi facing issue in rbd sop solver constrain . following a tutorial having issue in geometry spread sheet
angle is not showing in spreadsheet . check the image attached .

angle is one of the constraint attributes computed by solver

your timeline is on frame 1 and DOP Object by default have Solve On Creation Frame off, which suggests your RBD Solver hasn't cooked the object/constraints yet

so either go to at least frame 2 or check Solve On Creation frame on your RBD Packed Object DOP, or in case of RBD Solver SOP it would be in Setup/Simulation
