Arduino Uno R4 Wi-Fi not detected by Windows
Long story short, I was playing around with my arduino this morning and everything was working fine. I decided to change the wiring to experiment with a remote, and when I tried uploading my code, I got this error :
No device found on COM1
Failed uploading: uploading error: exit status 1
So I checked if I had chosen the right COM port in the Tools tab but I couldn't find one labelled with "Arduino uno R4 Wi-Fi" and none of them worked.
I have tried connecting my arduino nano to the IDE, and it got detected instantly, so no problem on the IDE side.
I know my cable isn't faulty as I tested it with another device and it worked perfectly fine this morning.
When I press the reset button the LED doesn't blink immediately but if I press it twice quickly it does.
I have tried remaking the setup I had before it broke and it didn't work though I think I just put it together wrong and I can't seem to remember how I did it. The arduino doesn't appear under device manager.
From what I have seen of people having a similar issue as mine, reinstalling the drivers might help but I don't know where I can do that.
Is my arduino dead ? If not, how can I fix it ?

Please carry out these steps:
Do complete Uninstall Arduino IDE and then re-install the Arduino IDE (use Arduino IDE 2.3.2). Make sure that you install all the dependencies that shows up after the installation. If your machine is running Windows 11, check How to Fix Arduino Problem on Windows 11 and grant the IDE admin right https://www.thecoderworld.com/how-to-fix-arduino-problem-on-windows-11/.
Install your board's Package Core, it contains the board's driver.
Use a good quality data USB cable to connect the board to the computer without anything connected or wired to the board. Charging/bad USB cable will make it impossible for your computer to detect your board.
Make sure you select the board and the port it is connected to before uploading a sketch.
If #1-4 above fails to solve it, double tap the reset button fast and check the status of the onboard "L" LED. If the onboard LED fade in and out slowly (pulsating), upload an example sketch (Blink LED) from the IDE to the board.
