Possible cause; Weak aux super capacitor (voltage converter) or weak 12V battery or both.

How did you figure an SRS Code is preventing your engine start ??

It just won't start. the car now is owned by my family member and he called me in panic. During video call he showed me the dash and it had SRS error, preventing him to start with the break pushed down.

I had him exit the vehicle close and lock and reenter to start and it started

you may want to have this looked at out of safety concerns: SRS/Brakes are now unstable for some reason.
