1. Have you actually checked the crash reports and logs folders, or is it just that the launcher doesn't give a link to the crash report? From what I've seen in other posts, the latest default launcher often confuses players about that. It's generally better to look in the folders.
It did not leave any crash reports, period. But it did leave a log, which I would provide but due to the way this forum works, I cannot provide it.
2. Did you try to configure Minecraft to use Java 9? When using Forge, that can cause Minecraft to crash without generating a log or crash report (I know from personal experience), but nearly all other crashes will generate some sort of log or crash report.
