Why all that? The purpose is to first identify the reason for faults. Solving that problem comes later. Wet and ring out maybe four bath towels - enough to be quite wet but not dripping. Hanging them to dry in that same room to increase humidity. Point is to discover if increased humidity (and therefore static electricity) explains this failure. Makes no sense to solve a problem until that problem is first defined.

Did you do what is always done to eliminate static electric charges - humidity?

Appreciate that safety ground nor earth ground are relevant to eliminating static. Static is a charge difference between any two parts. A ground for that must be one component of the system. Those solid or yellow striped green wires must merge at one part of the entire setup. Any connection to safety (AC receptacle) ground does nothing to discharge static charges. If static is a problem, then increase humidity to over 40% relative. If static is still created with high humidity, then move on to other reasons for misbehavior.
