Why do LED controllers fail when turned on / off?

Question

LEDs

I've come across a mystery that I can't figure out on my own.
I ask the community for help.
The following circuit is assembled:
First, 220 is supplied to the wall switch, after the switch, 220 is supplied to the power supply
eu.mouser.com/ProductDetail/Mean-Well/LPV-100-12/?...
after it to the
ledhouse.com.ua LED controller /p3284352-controller-rgb-12a.html
from it is already on two tapes powered in parallel. Tapes of 3.2m and 1.4m.
Plus, wires are brought out for two more tapes, but the tapes are not connected.
All wires on the site are either soldered or crimped with sleeves. Everything is isolated!
The essence of the problem: I turn on the backlight switch on the wall, the boiler works, the backlight works. Everything works as it should - everything glows and the colors change with the remote control.
But it's worth clicking 5-8 times in a row with a switch on the wall as the controller fails. At the next moment, the tape goes out no longer lights up.
At the same time, the light on the controller is on, indicating that power is being supplied to it.
At first I thought it was a defective controller. I phoned the seller - sent him this one back, and in order not to stand idle I bought exactly the same one. And I was terribly upset when the same story repeated itself.
Now I don't know what to think:
1. The power of the tape - everything is taken with a large margin. And a 12A controller and 100W power
2. Faulty series of controllers - I doubt that this can be directly
3. Faulty power supply. Here I'm not sure. Can it give out any jumps when turned on / off? I measure the output with a tester - voltage 12.1-12.3
To correct the situation, you need to find the cause. And nothing comes to my mind.
How to be? Where to dig?

Answer 1

If I were you, I would look in the direction of limiting the voltage (protection against its short-term surges - impulses significantly exceeding 12 V) at the output of the PSU (it is also the input of the controller). I think the optimal "cut-off" threshold is 15 V. Keywords for search are zener diode, stabistor, varistor.
The problem, most likely, is related to the features of the circuitry used by the PSU.
