But this is the third software flaw to be discovered and reported since the 737 Max crashes, which killed 346 people. Months after the fatal flaw was discovered, Boeing encountered another problem that prevented the flight control computers from starting and verifying that they were ready for flight.

According to Bloomberg, Steve Dickson, the head of the Federal Aviation Administration (FAA), told reports in London that a certification flight will occur in the next few weeks and that the FAA is evaluating this latest software issue. Even with FAA approval, it could be a long time before the 737 Max returns to service. In the meantime, Boeing has frozen 737 Max production.
