Use `GetSelectedExecutionContext()` instead of `GetCommandInterpreter().GetExecutionContext()` in `SBDebugger::GetInternalVariableValue/SBDebugger::SetInternalVariable`. The execution context in the command interpreter might be empty, if no commands has been executed yet (it is updated only when handling commands or completions -- e.g. https://github.com/llvm/llvm-project/blob/main/lldb/source/Interpreter/CommandInterpreter.cpp#L1855).
