Based on the crash report, this is a null dereference at

debugger/core/adapters/dbgengadapter.cpp

Line 793 in b313411

if (const auto result = this->m_debugControl->SetEngineOptions(DEBUG_ENGOPT_INITIAL_BREAK); result != S_OK)

when calling a virtual method on this->m_debugControl. It looks like Start() can fail and leave this->m_debugControl null.
