If it happened all at once, there certainly could be a leak, but it could also be a fuse.
I attached a pic below of the under-hood fuse box. I highlighted two fuses to check and the A/C relay.
When checking the fuses, confirm they are good first. If they are, confirm there is power to and from them. Here is a link you may find helpful:
If both fuses are good and have power, remove the A/C relay, and switch it with another relay having the same part number. If that allows it to work, replace the relay with a new one. If there is still no change, then we have to try to see if it lost Freon. In a shop, we connect a vacuum pump first to see if the system will hold a vacuum, but you don't have that to check. So that means you will need to get Freon at a parts store and see if it will take and hold the charge. Here is a link that explains how that is done:
Let me know what you find, if you have questions, and what I can do to help.
