V3 of the BLTouch has an [Alarm Release & Touch mode](https://docs.wixstatic.com/ugd/f5a1c8_77037f55e5d542309d9fc178165c9f3f.pdf) to activate after the probe is deployed. If this mode isn't activated, the BLTouch keeps deploying, ends up detecting a collision and gets itself in error mode.
Tested on a Creality Ender-3.
