Corrupted file during session

Hi all,

I am on Windows 10 platform run VScode. I am currently enrolled in Django (part1 and part2). As I followed along with the lesson, created the project environment, things seem to go along well. But all of a sudden, my file has a syntax error on the middleware “=” sign. I know this “” is cased sensitive, but can not find where the syntax has gone wrong. So I had to trashed the file and restart everything from the beginning of the lesson. Is there anyone who experienced this?
