Failed to pair: org.bluez.Error.ConnectionAttemptFailed.
I am trying to connect my Bluetooth joystick controller '8bitdo Pro 2' to my RPi4. Below is the error I get. This appears to be the same error I have seen constantly asked about since 2014 up to the present day. Why are we still asking it?
I did once get a connection but other events took over & I started a new installation. Having spent 3.5 out of 4 months on this project it looks like I will lose time & considerable expense. There are many answers given, some simple others complex, but none have worked.
My controller connects via the 8bitdo Ultimate S/W on Windows 10 & has connected using approxeng_install_show_controls on RPi4.
I have followed Approximate Engineering - Input - Command-line tools meticulously. It connects to the RPi taskbar icon.
At 78 years I need some help before it's too late.

With thanks to anyone brave enough to provide an answer. PS the text was formatted when I wrote it.
Thank you for your further suggestions. I tried 'remove' without success & looked at the Sony wiki. By chance I realised I had started afresh & therefore the 8bitdo pro 2.yaml file was missing from the hidden folder .approxeng.input. I originally had this problem when first successfully connecting. It seems approxeng when generating this file does not write it to the correct folder (though goodness knows where). Fortunately, I run with a USB memory stick and save code, etc if needed. A 'find file' gave me access to copy & paste it to the correct folder. So without using bluetoothctl I rebooted & hey presto!! I still have issues with buttons & the l2/r2 sticks but hey ho tomorrow is another day. My robotic vehicle now roams independently on the kitchen floor. thanks.
