So, I ran into this issue for the first time today on my v3 plus. Had it for over a year and 1100+print hrs so far. I had the code, and noticed some odd inconsistencies in my prints before the code kicked it off. Tried calibration of input shaping and leveling, nozzle wouldn’t contact the bed and just go up. I ended up taking the bed plate off, unplugging the level sensor and strain gauges and all of my problems went away after reassembly. We will see for how long, but the gauges and level sensor are under 50usd for a kit so if required I can replace.
