I need help,

bme680.py

Boot.py

main.py

while download&run main.py its stuck at

Ready to download this file,please wait!
......................
download ok
exec(open('main.py').read(),globals())

I've searched on the internet, but still can't find an answer.

Please help

You did not tell which boar you use. But for most boards you have to upload your python scripts only once. Then they are permanent on the board (until you replace them) and will be executed at every boot.
P.S.: It seems that in your post main.py and boot.py link the same content.

Sorry in advance, I've updated. I'm using esp32, could it be because it's flashed too often? every time executing web server always stuck. Tengkyu for your answer sir

Unlikely. The typical flash number of flash write cycles is 10000. But that is a worst case number, and even that is sufficiently high. In an attempt to write until the flash fails, I achieved more than 1 Million write cycles.

thanks in advance, is there any solution I can do for the case of esp32 stuck when "download and run" webserver on main.py, when the process is canceled and then restarted, OSError 112 appears. Which port is already in use even though main.py is not executing
