My DefaultEngine.ini File is Corrupted

After trying to submit the DefaultEngine.ini file to my Perforce sever the file suddenly became corrupted.
The Filetype of the DefaultEngine.ini file in Perforce is correctly set to “text”.
The change I made was integrating the steam online subsystem, this worked fine locally but as I tried to submit the file to Perforce this happend:

now I cant even connect to the Steam system locally.

thank you
