Affected version: 2.0.757 (Windows)

The bug

The launcher erases the profile directory if it does not exist. The expected behavior is that it leaves the set directory untouched and shows an error when you try to start Minecraft.

Note: The launcher accepts valid file paths however even though it cannot launch because it requires a folder path.

How to reproduce

1. Start creating a new profile
2. Enter an invalid profile directory
3. Save the profile and open the editing window
   → You will see that the profile directory is empty
