FFmpeg can't read a video stream, but VLC reads it fine

Question

I have a video stream that I can access using VLC, but can't access with ffmpeg. This used to work before I moved onto using a new computer (but with same camera).

This is the ffprobe command (made up IP addr):

ffprobe -hide_banner -rtsp_transport tcp "rtsp://root:[email protected]:80/axis-media/media.amp?event=on&eventtopic=onvif:VideoSource/MotionAlarm/."

It returns

rtsp://root:[email protected]:80/axis-media/media.amp: Invalid data found when processing input

I've not found very much on this problem:

• I've tried turning it off and on again
• I looked through this github issue but there were no solutions
• I know it supports TCP since it's the same command as when it worked last time.

Any ideas how I can get ffmpeg to read the stream?

Edit: Output of -report below, I'm afraid it's not very helpful:
