The most I can tell is this seems significant...

Stack backtrace:

[65942944] signalSemaphore + 0xd64 in ProcessWrapperPlugin.DLL

[659422CA] signalSemaphore + 0x6ea in ProcessWrapperPlugin.DLL

Smalltalk stack dump:

��0x11f8f84 M ProcessWrapper>finalize 0x8cb4fb0: a(n) ProcessWrapper

��0x11f8fa0 M WeakFinalizerItem>finalizeValues 0x8c94148: a(n) WeakFinalizerItem

Can you upload your PharoLauncher image somewhere for others to try - although the change in environment might disappear the error.
