Debugging progress for the Kalman filter:
✅1. Discovered an error affecting the reconstruction: EigenStepperError:3 (Step size adjustment exceeds maximum trials).
✅2. Examined the `step()` function of the Propagator (`Acts::EigenStepper::step(state, navigator)`) and identified that EigenStepperError:3 is reported even when the number of propagations is not exhausted. The issue is related to the initial 3-momentums.
Note: These 3-momentums are calculated by the SpacePoint in other Seeding algorithms, and truthParticle is not necessarily required.
✅3. The `step()` function implements the Runge-Kutta method for solving differential equations, determining the step size and calculating the error. The EigenStepperError:3 indicates that the calculation error consistently exceeds the set tolerance. (max iteration: 1E4)
☑️4. Identified all variables updated by the trial Runge-Kutta function during each iteration.
Currently, the crashes mainly originate from mathematical operations. The next step involves considering spatially rotating the truthHit in the DS coordinate system. This approach may lead to obtaining a safe initial seed.

Photon_ID_with_EE:
I'm preparing a standard form of the root file with correct closure tests and Fragmentation photons uncertainty, I expect it to be completed tomorrow.
Higgs to Zy analysis:
I'm rewriting the code for drawing dynamic distributions to make it simpler and easier to modify. Expect to see the kinetic distribution with the complete mc21_13p6TeV:ggF_H_to_Zy data set this weekend.
