I think I need the bin file to make it work again. I have an Ender 3 pro. Can anyone offer me some advice on this matter?

The .bin file is the firmware your printer is still using. After flashing the firmware it stays on SD card, so you can backup it. This works as the board only flash the .bin file with the latest date stamp.
So the next time you update your printer and something fails you can use that file to fix your printer. So you managed to kill your "backup".
SKR boards use a different approach. They rename their last flashed file to "firmware.cur", which is quite handy.

I wouldn't worry about it. The odds of your printer losing its firmware are very low. If it does happen, you can just download the latest release using your computer. Bear in mind, you will have to use something like the Arduino IDE to burn the firmware to the controller.

Just make sure the next firmware update does not fail. If it does you need a working copy from another ender3 user.
It is like a spare door key. You keep it safe to get back in, when you are locked out and when the door lock gets replaced you replace the spare key as well.
