No idea if it's the cause, but I noticed the path C:\Users\projects\xprojects\code_simu\code..\simulation\output\EPout.csv. Sometimes when the file path is really long on Windows, it can cause weird behavior. Maybe you can try moving your simulation files so they aren't buried within so many subdirectories?

EDIT:

I actually just hit this error myself. Another possibility is that the EPout.csv file from a previous run is open in an application (like Excel) and therefore EnergyPlus can't write the new file.
