Hi All,

I have been having a really weird issue with the Fenix lately that even their support can't track down. I can start a flight with zero issues and whenever I get to my destination and park at the gate something triggers the aircraft to completely freeze up, for instance I can shut the engines down and the switches in the cockpit will go too the "Off" position and the engines keep running sometimes the displays show minus values but just keep running, at this point the aircraft is frozen but the sim keeps running normally, I can manipulate the heading or altitude dials but the displays do not reflect the change, I can move my TCA side stick and the actual flight control surfaces move but inside the cockpit the side stick will not move.

Yesterday something even weirder happened, I did another flight and this time the entire cockpit froze as I was about to turn onto finals. The autopilot was still controlling the plane and the displays were updating properly but not a single switch, button or dial worked in the cockpit. I dropped the landing gear and heard the wind resistance as they were lowering but from the outside view they were still up. I disconnected the autopilot and was able to hand fly but no flight surfaces were moving. I re engaged the autopilot and decided to continue, only the main displays were all working. 

I switched to an outside view again and the gear was down and back in the cockpit everything was working again. I landed and parked at the gate and the engines shutdown without issues and everything was working as it was when I departed. 

I have tried emptying my community folder and adding things one at a time to try and track this down to no avail, about a week ago everything was fine, I removed the Fenix completely and re installed it and it is exactly the same, I am starting to think it is the sim that's the issue and I am thinking I may have to delete it and start over. I haven't seen this in other aircraft but to be honest I have only been testing in the Fenix A320 as that seems to be the main issue.

Just wondering if anyone else has come across this before I Nuke the sim and possibly Win 11.

Why? Why this childish behavior all the time? In any problem reinstall Sim and OS???

The problem is well known. It's extremely random and unpredictable. Fenix has no idea at the moment what is it. Join their Discord!

Known issue that affects many different complex aircraft. Some have had hotfixes to reduce the chance of them occurring.

Possibly a Simconnect issue. A full solution is unknown at this time. A reinstall will do nothing for you.

I have been troubleshooting something that sounds similar. I only use the Fenix A320 and my whole ecosystem seems more delicate after the most recent update.

In my case fixing it / minimising the issue seems to involve a combo of:

1. Untick all the options in the Fenix app interface

2. Turn off USB selective suspend power (in the Windows "performance" options)

3. Turn off GSync

4. Remove as many USB devices as possible (in my case, a couple of old joysticks still plugged in)

5. Stop using the Lossless Scaling app to double the frame rate on top of native frame generation.

Exactly! Remember the iniBuilds A300 falling out of the blue (skies) even after 4 or 5 updates.

I'm really sorry man but this is a complete placebo. Just wait for the next crash.*

My own guess is the plane somehow loses connection with Fenix servers which causes this behavior. Since version 2.2 they made more sophisticated installer to prevent possible cracking probably. May be the plane needs permanent connection between apps and servers who knows. If so Fenix will never recognize this problem just fix it quietly.

* Since it's not a real plane or Sim crash (CTD) Fenix logs are pretty useless.

Seems a bit drastic. Apart from #2 on your list (which is very good advice for everyone), I haven't had to do any of the rest.

I wonder if you and @RJC68 are running lots of objects that work through Simconnect? E.g. Lots of AI traffic, ground vehicles, passengers, anything else that moves.

Once I turned off yachts, fauna, and reduced the number of AI aircraft and GSX objects to a minimum, I had fewer cockpit freezes.

Just a thought.

Why?

Leaving the power saving feature on for USB ports has been known to cause issues in MSFS.

There's no need for that Windows feature to be active while flight simming.

This thread sent me looking at the Fenix Discord channel. I don't find it very easy to navigate 👴 but eventually I came across a suggestion to revert to Nvidia driver version 556.12. 

Worth a shot - and no issues so far.

Promise us to tell here when you have the next "crash"

I think I've directly told you twice or thrice now that this is not possible and spreading your theories around knowing I've told you this isn't how it works makes me wonder what you're after here.

I have been communicating with support for over a week now and not one mention that this is a well documented issue !

I was on Discord yesterday and one other commented that they were having the same issue. 

Hopefully this gets fixed soon, up until now the Fenix has been the most stable and best performing complex add-on I am glad I am not alone

I use FSLTL traffic, mostly to populate airports and don't typically have AI traffic in the air turned on, I have no road traffic either. I did try without GSX & FSLTL but still had the issue. I thought I had narrowed it down to a problem with MobiFlight but that theory was dispelled over the weekend.

Maybe I will just take a break from the Fenix for a while, I certainly haven't seen this in the 777.
