NTW doesn't start anymore

I was busy testing mod yesterday, and suddenly the game stopped to launch

I just got a window outline and it close immediately.

I tried checking the cache, it reinstall a few files. Still doesn't work.

I removed all my mod files. It still doesn't work.

I get no error message to explain the problem, the window just close immediately.

Anyone with the same problem?

Opt into the steam beta or try offline mode dude

That's what I did before, but I no longer have an option to sign for Beta .

Delete the scripts folder?

Try going offline?
