As the title says, the sim freezes some 5 seconds after it loads. The music is still playing, mouse is active, but I have to shut it down either through Steam or Task Manager. I let it be for half an hour to no avail. Nothing has changed after my last successful flight, no Windows updates, nothing. Except Navigraph updates.

I have a MAG B650 Tomahawk mobo, a MSI RTX 4090, drivers are 566.36, no Nvidia app, no GeForce Experience, 64Gb RAM. Later drivers gave me CTDs as well as did the new Nvidia app.

I tried:

- Deleted all Nvidia caches, also DirectX cache

- Community folder is empty

- in C:\Users\-user-\AppData\Roaming\Microsoft Flight Simulator 2024 I deleted Content.xml, exe.xml, UserCfg.opt, FlightSimulator2024.CFG

- in C:\Users\-user-\AppData\Roaming\Microsoft Flight Simulator 2024 I deleted Cache, SceneryIndexes, SimObjects\Airplanes, WASM\MSFS2024 folders

- deleted ROLLINGCACHE.CCC

I tried disabling DLSS in Nvidia inspector, tried to swap with earlier DLSS libs (3.7.0 and 3.7.1)

I also tried the latest beta (this morning) and then opted out again. 

Any ideas, has something like this happened to anybody? I seriously doubt reinstalling would solve anything, but I'll try that as well, since I am out of ideas. 

Thanks!

EDIT: Forgot to mention: no error log is generated!

Best advice I can give you friend is to cut n’ paste your entire text above and place it squarely in a zendesk ticket if you’ve not done so already.  Good luck,

Thanks, I was thinking about that, yes. But after my last experience with their zendesk when nothing was solved, I figured I'd try here first... 🙂

By the way, MSFS2020 is working 100%, so I guess that will have to be my sim of choice until I can figure out what is wrong.

Sure.  Hopefully others can provide more technical resolution tactics.  Again, good luck.

Install Nvidia driver 576.02 (latest) and the latest SU2 beta (1.4.14.0),.ALL of my freezing/CTD's have been solved.  Just did a two hour flight with no issues.  I couldn't run SU2 with the Nvidia app installed, but that is now installed with no problems. Also DLSS 310.2.1 is working OK.

576.02 and SU2 beta 1.4.14.0 solved every problem I had!

Problem solved! I got the solution on the official forums and I am posting it here in case somebody else has this same problem:

"I had a very similar issue. Try to delete your cloud save files in Steam.
First turn off the cloud save funcionality in Steam, the navigate to your Steam\userdata\usernumber)*2537590* folder:
Here try delete first the remotecache.vdf file and try to load the game. If it still not working, go in the remote subfolder and delete the datausage, localprofile and profile_00 files.
For me it solved it, but if you delete all 4 files, you’ll lose some settings. At least your inputprofiles will stay, just have to reselect them.
Also make a copy of these files, and if the issue is solved, make sure to upload them on the Zendesk Support page wth the issue description to help the devs solve this."

@MrBitstFlyer, I will try what you suggest, hopefully the bugs are ironed out by now.

Thanks to both! 🙂

Try to delete your cloud data.

Just a heads up it'll delete all your key bindings and game settings and career progress/logbook
