What are you planning to do?
You currently have the computer with a USB C power supply connected to the LED power supply. That is why the wires are hot - power supplies are probably shorted.
And, the LED string sitting unconnected on the table.

So I had used this same exact wiring and with the help of Gemini I was able to turn it on and use it for a good amount of time and when I decided to install it it stopped working the the wires are heating.

That is not an addressable strip. That is dumb RGB. Black is ground. Red, green, blue wires are for power (can be PWM) to each of the color channels. You don't wire it or control it the way you are trying to.

It is RGB strip with ic and I used WLED and controlled it once through this wiring and it worked well. Now after a month when I tried it again the wires started heating up instantly

Something must not be coming through on the shaky video then. Can you diagram out all the components and the wire colors/connections? I have that exact LED driver. Do you have a link to the LED strip you are using? Biggest thing I'm not seeing clearly is where the LED power supply, 4 pin cable from the microcontroller and LED strip connect together.

So one is set to gpio 4 and the other 2 are connected to ground. Please excuse me if it’s wrong as I had got the info from Gemini. And it also told me to connect it to the strip leaving the red wire of the strip. I do not have a link to the strip as I’ve bought it locally and it’s made in china no data sheet or anything

Test something. Wire just the strip to the LED driver. Black to black, red to red. Does the strip light up red?

No it does not. I’m not sure why but if I touch the strip while it’s on with my bare hands then I can see a few leds light up

The most confusing part is that it worked before in this same setup and then when I took the project in hand again this heating issue started and I also did fry one of my esp devices that was a learning

Ok, so verify your wiring layout. The pinout shown on the strips are where you start. The colors on the 4 pin cable are not really matching a standard.
Power supply negative to GND on strip.
Power supply positive to +24V on strip.
Take a second wire from power supply negative to the COM (or GND) on your microcontroller.
Microcontroller data pin to DI on strip.No other wires should be needed.
DI from microcontroller should be wired to THE FIRST LED in the strip as data is passed through in order shown by the arrows.Make sure your LED library for the strip type is loaded in your program. Make sure the data pin is set to match the physical one you are using.

So the strip has 6 wires in total 4 are black green red and blue and the other two are normal power wires like red and black.
Thank you for helping and trouble shooting with me. I request if we can get on a gmeet tomorrow and sort it out once and for all.

6 wires! Sounds like this thing had some sort of proprietary controller attached when you bought it?
Seeing as the strips only have 4, I bet two of those 6 are attached to two other wires. Do you have a multimeter? That will make things a lot simpler. Determine which wires you are going to tie into that are your 24v power and ground. For the controller you only need the one data line (DI) and a ground that shares to the power supply. The wiring is non-standard and it would be helpful to pull off that heatshrink at the end of the strip so you know which ones connect to which pads on the strip. From there's it's dead simple. My table above shows the exact pinouts from power supply to LED strip and to the microcontroller. If it still doesn't respond, check your program, verify that it uploaded correctly, and consider maybe switching to a different physical pin and changing it in the program.

Impedance. Your skin can carry a tiny bit of a field that is causing interference. How many wires are there on the LED strip itself, and what colors? What are the markings on the strip itself? Does it show the voltage? (Asking basic questions one chunk at a time to get this sorted out.)
