Alright so deleting the build directory and relaunching worked to resolve the above error! Thanks again. Although it turns out when I reached the 70% mark it just crashed with linker errors, which are different each time I attempt to rebuild (I kind of expected it because my pc only has 16 gb RAM, probably needs more since overhead of WSL/docker)
I initially tried builing directly on WSL only, but linker errors made me want to try experiment with using docker. So now i know that memory is actually the issue
The easy solution is probably just to work off a different system since my ram is soldered to the systemboard (non-upgradable) 
seoncd solution would be playing around with compiler flags to make the build take up less memory perhaps (tried this with few flags, still in process to find a flag combo that works)
