Custom ESP32 pcb boot issue

Hi! This is my first esp32 pcb for a simple pyrotechnic trigger for a rocket parachute. The board is working but the only issue is I need to press the reset button everytime for the esp32 to start running the code. I found that removing the capacitor C1 at the reset button solves this issue, the code starts running on boot, but i can't go into programming mode by holding boot and pressing and releasing reset without the capacitor. How do i fix this issue? I can't press the reset button everytime i need to power the board on.

For power i have an LM7805 converting 2S (7.4V) battery voltage to 5V and an AMS1117 converting the 5V to 3.3V.
