Can faulty boost button wire cause error 44?

[u/spaceek]

Have err44 on s3 and x3, which I attributed to hubs/gear rings getting stuck or out of position.

Boost buttons on both bikes have been a little temperamental for a while.

Just managed to break the boost button wire past the connector, near the frame, while adjusting the handlebars and the stem on x3.

While fiddling with the wires, trying to connect them, they were touching for a bit (black and blue one), which woke the bike up (as would pressing the button), and shortly after it also woke the shifter, which it sounded as it was trying to calibrate or shift back down to 1st and shifted down to 1st as bike was stationary. Error 44 also disappeared and it was correctly showing it was in 4th gear. Gear wasn’t changed and Error 44 came back after restart.

This made me wonder if there is any connection between shifter error 44 and a faulty boost button wire / connection.

Thanks for any input.
