This side path hardly exists, this is my best guess of where it starts...

Friends were not able to find this path ("it was literally not there") from the path to the North on 10 July 2023.

Pretty sure this track ends here, and there isn't a connection to the bridleway. Komoot (using OSM data) routed me down here once (approx May 2020) and just ran into trees. Not in the area to verify on the ground.
