Regular Crashes to Desktop (only in DX11 though)

[nuke74 1]

Dear Pilots!

For the last few weeks I have been experiencing regular crashes to the desktop with MSFS in the FNX A320, but interestingly these only occur in DX11. In DX12, there is no CTD.

The crashes always happen after having loaded into the plane, mostly a few seconds or, at the longest, 2 or 3 minutes after having loaded into the cockpit. The sim directly crashes to the desktop, no error message on screen, only a crash dump is present (parts of this: see below).
When starting the sim in the safe mode, it runs smoothly, no crashes regardless if I am using DX11 or DX12. Only when having all add-ons (see below as well) active, does the crash happen. I deactivated GSX to see if it helps, but to no avail. I fear that it is being caused by the Fenix A320, but there is no evidence for that.

To sum up, the crash always happens when starting a flight in DX11 with all addons active. It does not crash when running in DX12, also there is no crash in DX11 when I deactivate the addons (safe mode).

My go-to solution for the time being is to only fly in DX12, but there are drawbacks to that, mainly being the blurry/bad/default texture squares that appear on many airports and which look disgusting. I am aware this is a known DX12 bug, but there is no solution for that.
I would like to have the sim running  in DX11 again. With all Addos active, that is.

Anyway, this all happened after having installed the version 2 block 2, although I do not know if this update is the reason for the crashes. Anyway, the recent update from March 11 did not help to get rid of the CTDs.

Any chance for help?

CTDs tend to happen more often in DX12, so this is quite odd.  I would suggest that you clear your Nvidia  caches.  You might also want to clear any other caches such as rolling/manual caches if you use them (note that the Nvidia caches have recently been moved).

Also run a disk cleanup in Windows for the sake of completeness.

Yes, it seems quite odd to me...
Anyway, thank you for the hints, I will try to follow that any maybe also do a complete DDU re-install of the GPU drivers.

Update: Just completed a flight on DX11. I did all of the above mentioned activities suggested by cianpars and it worked. I assume the Nvidia cache was the culprit...

That would have been my first thought.  Glad you got it sorted 🤞

Many thanks for this valuable advice!
