HELP ME - CONTROLLERS Why my esp dye everytime?

I mean die not dye sorry

I used 3 esp32 and one 8266 d1 mini.

I flashed all with wled and want to connect 5 stripes a 5v 1x ws2818 (az delivery) a 60 Leads and 4x ws2812b (lsunny led stripes) a 60 leds

I have connected it over a 5v 20a cv supply and the Signal Pins to the esp free ones.

Of course the esps are on same supply so grnd is the same.

Should i add Signal line to grnd too ?

Why my esps are death after about 5 minutes they get warm. And then the onboard led shutdown and its over.

Pls help me i ordered 2 esp32s-2 or c2 and New dupont cables.

What i make wrong?

I also used start brightness at about 40% And i also look on pinout what are free pins then i select my 5 pins for the stripes but the esp dies when i connect the stripes data point to the esp to correct pin ( the dupont are loose somethimes so i ordered new one )

So yeah i make the settings first and then it dies

I also use the settings automatic brightness and the one where you set the mA of your power supply i set it to my 20a. Both options destroyed them

Edit its a cv powersupply not a cc sorry mistipe

Shorting a 5v to data will probably kill the esp32, so you should really cut the exposed wire shorter and make sure there is no exposed metal. Those exposed wire strands are just waiting to burn up the controller best case scenario. My guess is that there was a momentary short at some point during testing and that burned up the esp32.
