Greetings!

It’s been a while since I’ve run MSFS 2024 and I restarted it yesterday.

Do you get the safe mode prompt, if so will the sim start in safe mode?

Yes.

It tries to download in safe mode and still crashes.

Sometimes I get network errors on initial startup, but a network error shouldn’t cause the software to crash the entire system to a hard reboot.

5

How far along in the startup process (approximately) percentage ways does it get before this starts?

6

It get to the initial startup screen, (before the video), and about 30% of the time throws a 2046 error, (I thinks that’s right), which decodes to a network problem.

It continues to boot and goes all the way to the startup screen and indicates an “ongoing download”.

I go to the Marketplace => My Library and sit there. It doesn’t matter if I enable all the update downloads all at once or one at a time, it goes somewhere around 30 minutes and then crashes hard.

This crash occurs regardless of the initial error status. Sometimes I get download failures.

Even if we assume that a network error is the root cause, a network failure shouldn’t cause a hard crash to the bios.

There is a well known 1047 or 2047 error which is very similar.
One of the regular posters in the topic experiences the 2046 error that he has too.
Here is a link to that post: Cloud save error (error code:1047... and now 2047) - #71 by JumpyLand605315

There may be some info in that thread that may help as well.
