Second flight today without CTD without “LIVE WEATHER” set off in general settings of MSFS. Hope it will help you.
Good luck
Been plagued with CTDs this past week. Particularly this one flight I keep trying to do always crashes either during cruise or near the approach airport. Both airports load in fine separately with no issues. Ive now attempted this flight 4 times with no luck. I always receive these same errors from the event viewer. Yesterday just 1 time I had a CTD which did not appear in the event viewer.

Glad to see i’m not alone in this recent amount of CTDs that have appeared out of nowhere.
I appreciate the reply and it is a fair point however I would disagree with that. With the same pointer to the same dll causing the issue with the 347 error code. Something has to have changed on asobos side to cause it. I have seen so many people state that their sim has ran fine for a long time, they havent had an WIN updates or nvidia/amd driver updates. Anecdotal as it may be, its a loud anecdote to say the least.

During my livestream today I got 3 CTDs
- with no trace of GSX (it’s not GSX)
- Live Weather and Online Services ON
I then turned Online Services to OFF and also re-installed GSX and was able to complete a full flight. I think Karty has hit the nail on the head with this one. Something has affected the Online Services within MSFS - rather unfortunately at the same time GSX launched causing many people to rage unfairly at Umberto.
Just read further up that the Tech Team from MSFS have been reading this thread which is good to see also.

FWIW, I did a 2.5 hour flight in the PMDG 737 without any CTDs. This is with all the online options ticked, like I normally have. I don’t know why some people are getting them continuously and others never (like myself). I’m not convinced it’s related to the online services, as the random nature of these CTDs can make it hard to come to an actual cause and effect.
After completing 2 flights without CTD yesterday (never had an CTD before since I’m on MSFS since June), today I got a CTD, too.

After that I tried another flight, this time with live weather off, and I was able to sucessfully complete the flight after 1,5h.
None of us know what’s causing it but when people who never have issues are experiencing CTD after CTD, its highly unlikely that this group of people just happen to have experienced some sort of hardware failure at the exact same time frame running just this one application. It is more likely that something external is the cause.
The reality is that the sim is unstable in some ways, memory related issues for example continue to be a problem and there is no way for end users to even begin to trace what has gone wrong and why either.

This is a problem with Windows OS in general. It’s layers on top of layers. Basically still just DOS behind it all. Macs are so much more stable!

No question that there is a heap corruption bug (which may or may not be caused by Asobo), but having read through this thread, I know that you are getting it and hobanagerik and maybe a few more, but beyond that? This thread purports to describe a massive issue that everyone is suddenly having. However, what I suspect is that there is a bit of groupthink going on as everyone who is encountering crashes is contributing to this thread without understanding whether they have the same issue.
This isn’t an “I’m getting crashes too” thread, folks. If you don’t know how to confirm that you are encountering the specific heap corruption error in ntdll.dll, then don’t post here.

Had two CTD`s in a row while trying to fly from EFHK to EETU. Both happened in the same location while entering the Estonian airspace. Plane was FBW A32NX. Live weather on. The event viewer says the same as all the others, faulty model is ntdll.dll in System32 folder.
But the “can’t read memory” thing (FFF and 000) must be connected. It all started happening at the same time.
back flight EDDK - EDDB with Live Weather, VPilot, Acars, Google Maps Enhancement, GSX, in VR an again no CTD.
and that one has its own thread, that currently has more votes, so it would make more sense to post/vote there, to give it more chance of getting its priority raised.
If you haven’t already of course.

The “memory could not be read” error is a separate issue and there is another thread for it (see link below). This topic is specifically for CTDs related to ntdll.dll that started appearing within the last 48 hours or so.
Everyone: if you are getting crashes of the “memory could not be read” type, please post in the appropriate thread and keep this topic solely about the ntdll.dll crashes. Thank you.

Unless is it the exact same line of source code they probably aren’t related. Even if it is, a NULL pointer dereference and an integer overflow/underflow will generally have different root causes.
Same experience here. Never had a crash in almost two years, fired up MSFS today without any new modifications (NO SU10 beta, NO GSX PRO) and I had two CTD in one hour. Baffling.

Oh 100% which is why I made a point of posting the exact fault path from the entry(well one of several of the same Critical entries) from Event Viewer that shows. I guess some people might not know how to get to that area of the OS so I see your point and its reasonable. All we can hope for is the devs can dig into this somehow
Today i have the same errors its so annoying i have tested literally everything but nothing works ! One time i ve got the “can’t read memory” error but the other many times ive got a CTD… very strange if iam right its since ive installed GSX Pro but idk if this is the Problem
FWIW, I completed over four hours of test flying yesterday after I saw this topic trying to reproduce this CTD. Half of that was with live weather off and the other half was with live weather on. My sim remained rock stable the entire time. So while this crash does appear to be affecting many people, it’s not accurate to say that everyone is suddenly experiencing it.
As of this writing, this bug report has 110 votes, and 156 unique users have replied to this thread. While we are absolutely treating this very seriously, and I’m not trying to diminish the severity of this CTD in any way to those of you who are getting the ntdll.dll crash, if it was indeed affecting every player, there would be significantly higher vote and reply numbers for this topic.
