CW3 not launching - Linux 64-bit

[steelwing]

All of a sudden CW3 is failing to launch.  I'm on Linux 64-bit.  Neither 32-bit CW3 nor 64-bit CW3 will so much as show me a window. :(
Double-clicking my shortcut on the desktop makes the executable show in my task manager applet, but it immediately closes again.
I've tried running the game from the terminal as follows:
1. CD to the game's install directory.
2. Run ./CW3.x86_64 with the following results:
Set current directory to /opt/CreeperWorld3
Found path: /opt/CreeperWorld3/CW3.x86_64
Mono path[0] = '/opt/CreeperWorld3/CW3_Data/Managed'
Mono path[1] = '/opt/CreeperWorld3/CW3_Data/Mono'
Mono config path = '/opt/CreeperWorld3/CW3_Data/Mono/etc'
3. Run ./CW3.x86 with identical results.
This is all with CW3 version 2.04.  The last thing I did was start a Prospector Zone level.  I was about halfway through it.  I don't recall which system or planet it was.

What does your whole log look like?
~/.config/unity3d/Knuckle Cracker LLC/Creeper World 3/Player.log

There may be something in there that sheds some light.  Also, I assume you've done a full OS reboot to rule out any odd GPU state issues?

Not yet, I hadn't.  I did find ~/.config/creeperworld3.  And since it appeared to only contain settings, I just deleted it outright and then tried to open the game again.  That seemed to do the trick.   :-\
