Chrome Unpacked Extension Disappears

Question

I am currently developing a Chrome Extension, i test it as an unpacked extension in dev mode, normally the extension remains connected when restarting chrome, however suddenly it is removed every-time i close chrome with no explanation or indication that something is wrong with my extension

Any ideas what went wrong, or why this may happen?

Thanks

What worked for me, after having lost 2 days trying almost everything:

1. export your bookmarks...
2. uninstall CHROME
3. delete C:\Users\%USERNAME%\AppData\Local\Google\Chrome\
4. install CHROME
