In my case inversely I can fly into all USA and South America airports, but in Europe cannot  get to french and swiss airports. No problems with Spain and UK, must try Germany.

Really strange

Really strange

Problems also at Germany

And then the sim freezes and needs to be killed at the task bar

I just tried LOWI (Orbx) with the TBM (with Mugz TBM improvement mod, and WT G3000) and loaded in just fine. I took off on 26 and after climbing out turned north over the mountains to right downleg for landing on 26. Had no problem with fps locked at 35. No scenery problems, perfectly stutter-free and never budged from 35fps. I run mostly high settings, a few on medium and 200/200 lods. As you can see from my specs I'm not running a hotrod computer.

I did see a couple of really odd aircraft textures on the ground at LOWI - one was a multi-player C525, the other was a cub. Don't have time now to post pics showing the textures, but tomorrow I'll edit this post and add the pics.

Have you guys tried turning on dev mode before attempting to load into a non-working airport?

Pics taken at LOWI (Orbx) - What the heck is this?

Above and below are the same multi-player aircraft

This one is a static aircraft.

All others on the ramp seemed to be okay.

Yes, I always tried with Dev mode on 

I have the same problem when loading in EBBR.

Changed to a C172, and now EBBR is loading! With the G36 it froze halfway through.

So try changing plane.

Tried with C172, and no way, the issue is present

Last idea I have to try and get you into these airports.

Before launching MSFS:

In   AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache  find and rename the folder SimObjects, and the file Content.xml

Launch the sim (SimObjects and Content.xml will be rebuilt) and load into an airport that hasn't loaded for you.

I sent a request to Microsoft FS Support, which was answered very fast , and this is what I got:  "Thank you for contacting Microsoft Flight Simulator Support today. Do you have any third party scenery installed for this area? We have seen some issues with DLC since the latest update - in particular Switzerland mesh. There will be an update by month's end which should address these issues."

So I deleted Switzerland mesh, which I had installed, and Bingo !,  now everything is OK. No doubt that it was the ofending element in my case.

Thanks MS Support

 

After a couple of weeks of immense frustration, I have some reflections if anyone is interested, on the situation where many of the airports we bought and enjoyed before, and other addons still do not work, and where CTDs are more likely than not.

Many of us have tried all or most of the suggested optimisations and no pattern overall has emerged to explain why this happens to some but not others. Any instability or issue with our own PC is of course going to destabilise an already unstable software platform, but that does not explain it,

Asobo has already admitted that SU5 CTDs were not fixed in the two HFs, and that they would be addressed in WU6 - so we know there will be little we can do about it. We also know that SU5 was a radical rewrite, and a fundamental reassignment in the way the sim works. They rushed it out - most of the issues we have been suffering from are theirs, not ours.

We know this because airports that loaded perfectly well before do not load at all, or do not load as they should. Updates in my experience have not typically affected airports in MSFS. My problems have not just been loading airports, and are also much less now than they were before, but places like SCEL, LOWI are still a real problem. This has been one of the worst experiences I have ever had with a sim update (including P3D v5 if anyone remembers...). 

I believe that the new feature where scenery and autogen only loads (then later unloads) in the direction you are looking, puts much more strain on the hardware, and is also probably bugged.

You can of course do a certain amount to minimise the likelihood of CTDS (in my case they are mostly the 00005 code, often with an nVidia driver graphics related file). For me lowering the GPU clock whilst not great helped, and also increasing virtual memory on the sims drive helped too.

All in all, trying to fix bugs and CTDs as well as adding a whole new region of scenery, feels to much too soon. Instinct tells us that Asobo really badly need to take a break and to stabilise their newly updated sim first, before coming out with further updates. Much as I would love a better DACH region, I don't care if the sim keeps crashing. 

Finally let's have a definitive list of addons (free and paid) particularly in the Marketplace, that are certified working post SU5/WU6. It's still difficult to find what works and what doesn't in many cases.

To me, the solution is not and will not be re-installing the sim.
