IDE Fails to Upload Sketch at Specific %

Development Tools IDE 1.x
1

I have run into a problem where my IDE fails to upload my sketch whenever it reaches ~90% (the exact value of this point is unknown to me but it remains the same every time). I am using the most recent IDE version and a Node MCU 1.0 board. I have tried reinstalling the IDE, and CP2102 driver multiple times, different cables, and even brand new boards. After each attempt the uploading of the sketch fails at the same %. I have included the log of such a failed upload at the bottom of this post, any help is appreciated.

Are you sure the ESP8266 board that you're uploading it to has as much storage space as you think? (what gave you the idea that we could solve your problem without knowing which of the many ESP8266 boards you're using? There are a huge number of different boards, with very different parameters)

I know in at least some configurations (I'm not an expert on what is done for Arduino on ESP8266 - I only use them with the Espruino f/w), the flash is split in half to enable OTA updates, and some of the space is used for an OTA bootloader. In that case, if you've got one of the modules with a 512 KB (4 mbit) flash, you'd run out of space at around 256 KB, which looks to be approximately where it's failing....

I am using the Node MCU 1.0 board. Additionally I have been able to upload this program to the board before without issue which would seem to indicate that it is not a memory problem.
