Produce a ReactOS debug log because ReactOS's behavior is what is in question.
See the instructions on this ReactOS Wiki web page: https://www.reactos.org/wiki/Debugging
Instructions for debugging when ReactOS is running inside a virtual machine are included.
The page includes a link to the page that describes how to set up a virtual serial connection from the VMWare virtual ReactOS machine target to the real machine host that is hosting VMWare. (The other virtual machines supported by the ReactOS project are also covered, but on web pages of their own.) People who run ReactOS in virtual machines find this method very helpful.
The instructions have not been updated recently. If you encounter problems search the ReactOS site for solutions. Use your favorite search engine and include site:ReactOS.org with your search string. If such a search does not reveal an answer, ask for more help here.
