Can't send file from phone to Windows 11 PC

I have a Samsung A35. My phone is connected to my laptop and both show that they are connected. They are both at least version 1.25. I tried to send a file from my phone to my PC, and my laptop shows up as being connected. I tap it to send the file and it says "Preparing to send... Stay on this page and make sure your PC is unlocked", but it doesn't do anything beyond that. My PC is unlocked and the app is open but nothing is happening. Any ideas?
