so I was using TexWorks and while running my ut.tex code to create pdf , my pc suddenly crashed. now ut.tex file has equal length to last version but it is all spaces (all in first line)
also if i try to run it again console output says: Text line contains an invalid character. l.1 ^^@^^@^^@^^@^^@^^@^^@^^@^^@^^@^^@^^@^^@^^@^^@^^@^^@^^@^^@^^@^^@^^@^...
note: i tried to use windows restore previous sessions but there were not any saved ones :(
