Autoleveling issue with BLTOUCH (no replies)

Suddenly, my Anycubic Kossel Linear Plus printer is sending the print head crashing into the bed whenever i run the G29 command.

Here is the debug log:

There is a strange call to do_blocking_move to -300 just after the bltouch is deployed.

Has anyone seen this? Any suggestions on what could be happening?
