09 Camry gas pedal stopped working and push start/turnoff button stopped working

Hello, it's quite impossible to know what's going on without a hands on inspection and evaluation using a diagnostic tool capable of interfacing with the affected systems. There could be a correlation, there may not be. It's impossible to know. The throttle is "drive by wire" so a wiring concern or throttle body concern could be present. The start stop button doesn't really interface here, but perhaps there's common wiring - troubleshooting will help figure this out.
