Debugger: Fixed crashes when switching between games from different consoles (in AOT build)
...
Caused by what looks like slight differences between how AOT treats an empty array (vs JIT builds) when it marshals the array (AOT sends a null pointer, JIT sends a pointer to an empty array)
This was causing issues in both builds (AOT crashed immediately because of the null pointer, JIT read from out-of-bounds memory)
