Default CH GFI breakers tripping, timers and dimmers malfunctioning

I am having trouble with a 5000 sq foot house i just trimmed out. The main panel is 200 amps. There is solar and 2 sub panels in different parts of the house. All breakers are from the cutler hammer series and are type CH. I have been experiencing GFI breakers tripping for no apparent reason. They wont be under load and will trip and cannot be reset. I used my meter to test for faults between hot/neutral, hot/ground and neutral/ground and do not have any issues with any of the circuits. I'm aware of nuisance tripping but there are quite a few breakers experiencing this issue and seems to be mostly related to GFI breakers. Only one or two arc fault breakers have tripped.
ALSO i am having problems with devices. The lutron timers and lutron maestro dimmers have gave me some problems as well. The timers under load will show voltage jumping all over the place and you can hear the fan speed go up and down. I replace with a mechanical switch and everything is fine. Voltage is fine as well. The maestro dimmers do not work as well. They will strobe and the pilot led's on the side of the dimmer will go up and down. I had spent hrs on the phone with lutron's head of technical support and all he could come up with was some kind of interference (I think that was his way of saying he doesn't know). It seems like any type of device that has a computer in it will not work in the house. All the wiring is correct. Everything operates correctly with mechanical devices. Voltage is correct except when using a smart device. I have turned off the solar breakers and still have issues with the breakers and devices thinking that maybe solar is interfering with my circuits
A little back story, about a month ago i posted on electrician talk about issues with getting zapped on trim screws in a certain part of this very same house. It turned out to be massive static electricity generating from a new shaggy carpet that would release on the grounded trim screws and would fry the maestros. The rest of the house is all hardwood though and on different circuits/panels. What in the world is going on here???

All decent power monitors are now digital memory based.

Did you check for neutral grounding issues lift all your neutrals and megger to ground. Isolate all loads 1st.

In my experience with GFI's they can be a pain in the but. Especially in a home that is wired typically but has all kinds of fancy crap added. Like Brian John said start dropping neutrals, I would have to take a guess that there are shared neutrals somewhere causing the problem. Also as he stated meg to ground, it is possible that a small nick is causing a low level ground short. I have seen this often in the way jackets are stripped off and wires are nicked, it does not appear until they are tucked in box and spread apart a bit. You said you just trimmed it and everything is good since you double checked, something in the rough-in is probably the issue. Unfortunately it's gonna be a circuit by circuit check and be a hair puller, especially since you mentioned multiple breakers. I would start at panel and lift neutrals and go from there. To be honest something is not wired correctly and from the way you describe the issues it sounds like you have a neutral to ground short somewhere. One last thing where are the problem breakers in main or subs. Remember that wires don't cause shorts, people cause them and careless and speedy results in problems. Knowing the rough-in crew can also be helpful, what kind of work do they do, how much pressure to get it done etc. will give you clues. Good luck.

The best high-speed monitors are digital and printing to paper is simpler than logging into this forum.

Digitally I can break a voltage disturbance down to sub-cycle and I am an old fart
