Arduino-esp32: ESP32 Keeps rebooting after code uploaded

[bhavish030]

Hello all,

I've seen the previous similar issues, but i don't know yet if there has been a fix to this since i can't really understand the explanations and i a newbie to ESP32. Very sorry for that but can anyone explain to me clearly, if possible, how to fix my ESP32.
These are the errors appearing on my serial monitor:

Am really desperate at this since i cannot work on my university project. Actually i have 4 ESP32 and each one of them used to work perfectly until last week 3 of them started to behave abnormally for no reasons.
I've been working on this project for 5 months and just in 3 days i've got my presentation and my ESPs decides to behave like this at that critical time.
If anybody can help me out to fix this, that would really save my life>.
Thank you

It looks like invalid partitioning. Try wiping one of the devices by running python esptool.py erase_flash from the command line. If you get the same error after reflashing, you have a problem in your code. Figure out where with the exception decoder
