If someone has this type of nRF24, can you measure resistance between GND and V+ pins using a multimeter? Mine shows that these pins are almost connected to each other, i think I have fired it.
I have one of these too but there is absolutely no connection between these pins
If doing the test gives you a resistance value, then dont keep it secret, do say what the resistance actually was plus the multimeter used. Measure in both directions.
We could all have different views of what 'almost connected' means ........................................
I had one nRF24 module (the low power version) with a short circuit between Vcc and GND. Just chuck your faulty module in the trash.

This is my multimeter
When I put it on "20K" resistance meter, it shows 0.75 in both directions.

Last night I could get it work but not quite well because my circuit had some problems.
After 2 minutes that I was trying to get it work in my circuit, I realized that the voltage regulator connected to the module, was so hot and made the module hot too (because of some short between pins in my board I guess), and today after repairing and resoldering my board, I can't get it work and when I turn on my circuit, the Arduino nano which is connected to the module, start blinking fast (like it says disconnect me from this damaged module 
), I think maybe the heat from the regulator caused this short in the module

Characteristic of a melted or carbonised blob then.

Sorry I don't understand, what do you mean by "blob"? I want to know if there's a way to repair/replace the damaged component?
Something between the VCC and ground is acting as if its just a blob or lump or short of something and with the same very low resistance in both directions, so no evidence of a semicondutor.
A resistance test across VCC and GND whilst it indicates 'something' has fused or melted is unlikley to identify the aflicted part.

Can this component be the problem? There is no resistance (zero ohm resistance) between its pins in both directions

What is printed on the component?
Measuring resistance when a component is on a circuit is never reliable - you have no idea what you are really measuring. And it may be a genuine 0 ohm resistor providing a link between two points on the circuit board.
I repeat what I said in Reply #2, throw the thing in the trash and get another one.

Nothing is written on it, I don't know even if it's a resistance, capacitor, etc. I thought it could be guessed with knowing the shape, size and color of it.
Yes I have no other way than buying another one but the reason that I was looking for a way to get this one work is that everything in my country, Iran, has a little more price than many other countries and I wanted to try bringing it back to life before deciding to throw it away and buy a new one

I can understand your desire to get the module working but debugging a problem with a device like that is not at all easy.
I think those modules are built according to a schematic and PCB layout in the Nordic datasheet for the nRF24L01+ It may help you to figure things out.
For myself, when I had the failed module and I could not see any obvious problem with a magnifying glass I figured that any further investigation was far beyond my skill level.
