I hooke my Arduino Nano Every onto a 12V Battery Pack on VIN and it got really hot. Then I disconnected the Battery Pack and connected the Arduino to my PC where it also went really Hot and i couldn't upload a Sketch. Did i break the Arduino or/and what could I do besides buying a new one?
Thanks for Answers
Schematic:
Probably. You could look at what is heating up or burnt and remove the part and replace but probably better buying a new one and reading the data sheets before hooking it up to stuff
Like when i googled everything said i could hook up a battery pack with up to 21V so...
Post a schematic of your connections

Your connections shown should not cause an issue. Note you actually should connect the GND to the pin next Vin.
Is there more to the circuit than showing? i.e. is there anything loading the board?
Could you have accidently reversed the + and - wires?
From the information you provided this should not happen.... so
Can you describe what part " it got really hot"?
definitely you can , but the problem is arduino nano main controller chip(ATMEGA328P AU) works on 5 volt and there is converter AMS117 on nano board which is converting the voltage supplied at VIN pin to 5.00 volt. Now here, AMS117 is a linear converter which means it is supplying you 5 volt but rest of the voltage is getting converted into heat resulting in heating the whole board,
Next time please try to use switching buck converter which will result in saving energy as well as safe conversion without any heat.
This thread is about a Nano Every, not a classic Nano. There is an mpm 3610 switching regulator on the Nano Every and its spec'd for up to 21v input. There is absolutely no issue with powering the Nano Every with 12v.
I almost burnt my finger. It hurt even afterwards. It was immediatly when i connected the battery
Then why did i almost burn my self when i powered it over usb 5v?
I've had quite a bit of experience with the Nano Every; initially I was losing about half during programming. I found that if I connect an external 5v supply to the VIN terminal BEFORE I connect to the USB port, I have no problems. If I don't follow this procedure, there's a 50-50 chance it will fry. Just sharing my experience with these, otherwise, really good Arduino's.
Do you know which part fails.

I have not bothered to determine which component is frying, but I suspect more than one component gets damaged or destroyed before the "burning" stops. The Nano Every's are inexpensive enough it's not worth the effort to try to repair them...if it burns, it's in the trash.
Something "kind of" shorted out, and whatever it was when powered it draws enough current to generate a local hot spot.
Still the only reasons I can think of are as I said, a previously bad board or something isn't what you think it was when connecting the 12V
As for why connecting it to 5V parts get hot. Best guess is a part failed (perhaps with the 12v) and once failed was still failed when connecting the 5V.
People are reporting failure when connecting a new board just to USB,
with nothing elso connected to the Every.
And "the board getting hot" (not a chip getting hot) could be the 3.3volt regulator,
because that is a part heatsinked to the ground plane.
The USB blocking diode burning is a result, not a cause.
The 3.3volt regulator is only supplying the USB chip.
The MCU runs on 5volt.
Adding it all up, I suspect that the 3.3volt regulator fails shorted to ground.
Would be easy to remove the regulator, and test if the blink sketch of a new board still works.
