Incorrect wiring would be my guess, and it probably killed your transformer so that may need to be replaced if it is no longer putting out the required power.
A stuck down doorbell button somewhere in the system could do it too, typically that probably would have seized up your chime too (and it would likely have been making a humming/buzzing sound for a while).
I think we’d need to know more about your system (transformer, chime, wiring, how you connected the Chime Controller, etc.) in order even to begin to answer. Was the doorbell working at any time after the initial installation? Providing information about the timing of the issue might be helpful, too.
One topic that comes to mind when reading this is Wired Doorbell Chime Sensor fried?, but the user who posted that apparently hasn’t ever returned to report any kind of resolution.
I also notice that you tagged your topic with cam-outdoor-v2, but did you intend to choose video-doorbell-v2? That’s the model that typically comes with Chime Controller, though it can also be installed to work with Duo Cam Doorbell.
Welcome to the Forum, @stevebab! 
Sorry, it is for my Wyze vidéo doorbell (sorry my English is not really good)
So my first one works for over one year…. Before its stop and its only when i change the new one that I realise that the chime contrôler have melted
Heres another picture of the Transformer
That’s the chime box (not the transformer), and you’re wiring the Chime Controller incorrectly. This is what you want:
- LEAVE THE WHITE WIRES THAT ARE NUTTED TOGETHER ALONE! DO NOT CONNECT ANYTHING TO THOSE! I believe that’s your main problem. Those wires are providing a “return” path to your actual transformer and would be represented by the continuous green wire in this image from the Chime Controller Installation Guide:
Remove the black wire from the FRONT terminal and use a wire nut to connect it to Chime Controller’s black wire.
Connect Chime Controller’s white wire to the FRONT terminal (as you show in your picture).
Connect Chime Controller’s red wire to the TRANS terminal along with the black wire that’s already connected there (as you show in your picture).
This is what you want to do if/when you obtain a new Chime Controller. I believe the way you’ve had your Chime Controller wired has actually created a short circuit, and hopefully the Chime Controller has acted as a fuse (which it’s supposed to do even when wired correctly) and protected your actual doorbell. If that’s the case, then correctly wiring a new Chime Controller might resolve your problem without the need to replace anything else, but I always lean into testing things myself (i.e., with a multimeter and/or other appropriate tools) when I can.
I am not an electrician.
Thank you for sharing this excellent photo! Things like that really help when trying to understand problems like this. 
Yes!
That’s much better.
One caveat is that it assumes that your FRONT and TRANS wires were correctly connected before you made the change. With my own Video Doorbell v2, I eventually ran into some problems getting the chime to actuate with a doorbell button press. Wyze replaced it for me, but then I did some additional testing that they hadn’t suggested, and in the process I discovered that the FRONT and TRANS wires had been connected to the wrong chime terminals when the previous “dumb” doorbell button was installed. Since I did continuity tracing with a multimeter and got the wires correctly identified, my Video Doorbell v2 has performed much more reliably.
Have you had a chance to fire it up and test it yet to see if this resolves the problem?
Yes, I tried It, nothing works 
Balls. What does your transformer look like, and do you have a means to test that? That might actually be hosed, as @dave27 suggested.
Somewhere in your house, you likely have something that looks like the picture in the Help Center’s Chime Compatibility Check article, which shows a transformer with “16V 30VA” output. That should have a black wire connected to one screw terminal and a white wire connected to the other screw terminal. If possible, that’s what I’d test and potentially replace. If you don’t feel comfortable with doing that safely and correctly, then I’d consider consulting an electrician.
Well now I think im going to check with an électrician, just to make sure
Thank you very Much for Your help ! Sorry again for my English

I think that’s a good plan. Sometimes even locating the doorbell transformer in a home can be a challenge.
You’re welcome, and no apology is necessary! I hope you can get this resolved and take the time to report back at some point.
