I tried to run MSF2020 and received the following message:
Encounter Donelo Crash
We are deeply sorry, you have encountered the “DonelO crash”. We are trying to recover so you can continue enjoying the simulation.
Can you please help us fix this error by going on DevSupport (https://devsupport.flightsimulator.com/), and providing us information about this "Donelo crash on the dedicated bug report category.
We received enough bug reports for our devs to investigate the issue so reporting is no longer necessary and the message you saw will be removed with SU15.
