help my save file suddenly wont load

[new2qr]

i edited my main save file before going to work, its been working perfectly fine with no errors for about a week, i came back from work and (without any changes to the file i edited earlier) it will NOT load into pkhex! i tried downloading the most up-to-date pkhex version and compared it to a working main file and they were both the same size

this is the error i am getting: attempted to load an unsupported file type/size

ill attach my save in hopes that the experienced members and/or creator of pkhex can help solve this problem..
