Hello,

I am trying to upload the code in esp12-e WiFi module but I am unable to do that.

But prior to this issue I was able to program the same module many times and suddenly it stopped programming.

I am getting following error
esptool.FatalError: Failed to read register address 3ff00058 (result was 0105)

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

did you by any chance update your arduino esp8266 core?
try going back to the prior version, unfortunately the switch to python flasher is a pita for most windows user.
