FYI the Msconfig tool may be helpful to isolate the exact service that is causing issues. I just wanted to disable everything to get through the install. If I have any issues while playing with everything enabled. I can take the following strategy:
It would take some time but what you can do is disable all the third-party services after hiding all the Microsoft ones and then launch MSFS to see if it works. Then jump back in and enable half of the third-party services in your list. Run MSFS again. If it works you know that those services you just enabled are not the culprit. Go back to Msconfig and disable those. Then enable the next half and repeat. If it did crash you know the problem is in that half of the list you enabled, so go back to Msconfig and disable half of those services and repeat.
Think of this as a type of binary search (or divide and conquer) to nail down the problematic service. It should take you log2 of n attempts through the list with n being the number of services you have to search through. That said if there’s more than one third-party service causing problems, it will complicate things
