[zero-w] Debug constant crashes

Hello everyone, i have come to yall as my last resort. My rapsberrypi zero-w just keeps crashing(?) every few days and i cannot figure out the cause or how to stop it. Ist running a simple discord.py bot that is supervised by the pm2 process manager. Every 1-3 Days it goes offline and refuses to do literally anything. I cannot interact with it via cable or ssh. After having to cut power [:(] to get it back running i tried sifting through journalctl but with no luck. After observing when exactly it went offline, then going back and checking that timestamp there is literally nothing logged at that time. I have tried completely whiping it and reinstalling the OS, didnt help. I have tried the watchdog (though admittely i had no idea what i was doing really). No luck. It is a new bought rapsbverrypi zero-w running pi-OS (not headless). Ive had the issue whether i primarily connect to it via hdmi and keyboard or ssh. Any Ideas how i could go about debugging this will be apppreciated 🙂

after searching this discord server i have ordered an official power supplay and will see if that resolves my issue
