Since first loading MSFS2020 from MS Store about a month after release, I have had a relatively trouble-free run, with only a couple of CTDs that were easily fixed by removing recently installed addons. However, some 2 weeks ago the sim failed to install and crashed after the first blank black screen (ie before the rotating load-circle appeared in the bottom right corner). At this stage I made the following changes:

 

- Empty Community folder – no change.

- Log out and back in to MS Store – no change.

- Log out and back in to Game Box – no change.

 

At this stage I gave up and abandoned the PC for a more productive activity ie mowed the lawns. An hour or so later I returned to the PC (with a cold beer) and, lo, the sim loaded as smoothly as ever!

Regrettably, however, this situation reoccurred several times over the next week or so and I reasoned that perhaps it was a server problem. Initially the server selection was set to “Auto”, with me thinking that if a particular server was down the programme would move on to find an operational data source; unfortunately, regardless of auto or manual server selection the problem returned to annoy! The problem has always cured itself after a couple of hours, up until the day before yesterday that is, when it was still failing to load after 18 hours. At this point I installed every optional Win 10 update available, immediately after which the sim loaded as smoothly as ever and continued to behave until this morning.....when it was (and still is) black screen to CTD again!!!!

 

I am located in New Zealand, so some distance from all servers, but this has not appeared to present any issue until this problem arose a couple of weeks ago. My fibre connection, as measured by Ookla Speedtest, currently runs at 180Mbps locally, 150Mbps US West Coast and 100Mbps London.

 

All analysis, suggestions or just comments are welcome.

Loading FS2020 continues to fail and this is the output to the Event Log:

Interpretation is well above my knowledge level but may provide some information to those out there skilled in such matters.

Some suggestions :

Have you connected any new hardware recently ? 

Have you changed any driver ( graphic card, controller etc.) ?

Check that all your controllers/headset or loudspeakers are firmly attached to the computer, no loose USB or jack.

Do you see this issue when you start MFS just after starting the computer or starting the game when the computer has been running for a while ? Or both ?

The above two items from the event viewer report are the important bits of information. It is telling you that there is an issue with the indicated DLL. The ucrtbase.dll is a part of the Visual C++ application. In your case, it is most likely a part of the Visual C++ redistributable package.

Try uninstalling all Microsoft Visual C++ [xxxx] Redistributable packages from Settings -> Apps. Then download and install the all in one package from here: https://www.techpowerup.com/download/visual-c-redistributable-runtime-package-all-in-one/

If that does not fix the issue, then you may want to try the steps indicated here: https://www.minitool.com/news/0xc0000409.html

Good luck!

I was having the same problem and tried every suggestion I could find...reinstalled Windows, deleted and reinstalled  sim, disabled virus software, firewall, you name it, and nothing worked. I was running Seagate's Toolkit backup and deleted it and low and behold, FS2020 loaded, updated and is now working perfectly. Have no idea why or what the conflict was, but deleting Toolkit ended a week of frustration.

Hope my experience helps...good luck.

Most of the time, uninstalling either MSFS or Windows don't do the trick.

Good morning and very many thanks to all the responders. Before working through the suggested actions first thing this morning, I clicked on the FS2020 launch icon and it loaded as sweetly as ever!!! Have shutdown and reloaded several more times and flown a Kodiak Island bush trip, all without any issue. I anticipate that the problem will reoccur at some point, at which time I will work through Visual C++ fix from JimBrown and report back.
