From the 4/1 statement by Ambassador Akram:

There is no number 6, in case you’re wondering..

This news report has details of the Indian Air Force’s explanation concerning the 2022 Brahmos incident:

In a statement submitted to the Delhi high court during a case, the IAF revealed that a court of inquiry to probe the incident found that “combat connectors of the BrahMos missile remained connected to the junction box” during a routine inspection, leading to the unintended launch. The junction box is a critical component that transmits firing signals to the missile.

The probe further highlighted the gravity of the situation. The combat crew were aware that the combat connectors were still attached to the junction box, but failed to intervene. Consequently, the mobile autonomous launcher commander launched the missile, posing a potential threat to airborne aircraft.

Bit late to the party, but here’s the DRDO press release about the Agni V MIRV test:
