Hello everyone 
I set everything up and the led not stable
when I change the color or the effects it starts blinking in annoying way I can’t share with you a video of the situation to clarify more 
.
The led is ws2812b ( 201 NO. )
5v 10A power supply
ESP32 the data pin is in ( d2 pin )
The wire is the defilt and i solder it with extension of ( 18 awg silicone wire )
We’ll need more details about your setup:
Type and number of LEDs
Power supply type(s) and voltages(s)
Wiring layout and size(s)
Controller used (brand, ESP32 or ESP8266)
Data pin (GPIO) used
Is a levelshifter used?
Version of WLED loaded.
etc.

How do you have it wired? Power/Data
Definitely make sure you have a ground wire from your ESP32 to the power supply and the LEDs as well as the data wire.
How long is the data line from the ESP32 to the LEDs?
Try another GPIO pin, maybe GPIO16 and configure WLED to use that.
Thank you 
I figured it out!
The wireing was ont stable
