Lately Max Verstappen was having start issues on Sunday and it seemed it was fine again in Russia. This weekend in Japan they have a fuel update and so they changed some software.
Watch the Red Bull driver having start issues again during practice in FP2. Afterwards Max said they were testing new software as mentioned and after 4 fails the last 2 were fine.
