You crash seems to be caused by a Helios script:

Thank you Flappie!

I will investigate.

Hi Flappy,

after Helios reinstall i found a solution.
In single player if the units is denominated 'Player' everything is ok,
if is denominated 'Client' ==> DCS crash

I have this issue too, never had before the 2.8.
It should be fixed

I have seen friends in VR crash to desktop flying the Apache. Think they fixed it by lowering the cloud option. Worth a try. Good luck.

Hi @Mercury_1965. Sorry, I had not seen your answer. What do you mean exactly? The issue is not caused by HELIOS? Please attach a mission causing the issue. I'll give it a try.

xfirf · December 9, 2022

I´m experiencing the same issue on self-made missions. When the KA-50 is setup as "Player" everything is working. But when I switch it to "client" to have several different Modules available to choose from at start of the mission the game crashes when selecting KA-50

Running on the latest open beta. Already sent some dx-reports after the crash

Edit: Added example-mission

Persian Gulf - Convoy.miz

Thank for the mission file. I cannot reproduce the crash.

@horus-DCS @xfirf Can you please reproduce the issue and then attach your dcs.log file? I need to find what you three have in common.

xfirf · December 10, 2022

Sure, here you are.

Many thanks. The culprit seems to be Helios for you as well: you're having the same Lua errors in your crash stack.

Please ensure Helios is up-to-date. If it is, you should report your issue here: https://github.com/HeliosVirtualCockpit/Helios/issues

Hey @Flappie,

the devs of Helios can´t find anything strange on their side. And as this only occours for some ppl are you able to provide more details as they are not able to debug DCS? It would really be cool if this issue could be fixed.

xfirf · December 12, 2022

Update.

When I replace some of the KA-50 files in the folder "D:\Program Files\Eagle Dynamics\DCS World OpenBeta\Mods\aircraft\Ka-50\Cockpit\Scripts" with the one from "D:\Program Files\Eagle Dynamics\DCS World OpenBeta\_backup.023\Mods\aircraft\Ka-50\Cockpit\Scripts" the game does not crash, but the graphics are messed up.

So from my point of view there was a change in the last update causing the issue?

Flappie · December 12, 2022

Helios is a mod for DCS, not the other way around. When DCS changes, Helios devs need to adapt their product to DCS.

Since Helios devs say only a few Helios users are reporting this issue, I'm guessing it has to do with your custom Helios config files.

Please attach this file:

Yeah, you described it better than I did, sorry.
My point is / was: A change within DCS "caused" the issue. Finding the right change will help fixing the issue.

HeliosExport16.lua

Flappie · December 12, 2022

Thank you. Let's sum it up:

1/ The game crashes at this stage because of a Lua script:

2022-10-28 18:43:52.038 INFO    EDCORE (Main): 0x000000000008CDB1 (FMBase): EagleFM::Elec::Lamp::getLightness + 0x21
2022-10-28 18:43:52.038 INFO    EDCORE (Main): 0x0000000000123513 (CockpitKa50): cockpit::Ka50::ccMainPanel::lamp_H_RALT_stab_controller + 0x53
2022-10-28 18:43:52.039 INFO    EDCORE (Main): 0x00000000001D6CF6 (CockpitBase): cockpit::ccMainPanel::set_arguments + 0x36
2022-10-28 18:43:52.039 INFO    EDCORE (Main): 0x00000000001D43BF (CockpitBase): cockpit::ccMainPanel::l_update_arguments + 0x4F

2/ And here's approximately where the Lua script crashes:

        local mainPanelDevice = GetDevice(0)
        if type(mainPanelDevice) == "table" then
            mainPanelDevice:update_arguments()      <--- crashes here, or so it seems

I was looking for info about this GetDevice() function... and look what I just found!

Same bug, 5 years ago, different aircraft. I think it's time to call for help.

Hello @cofcorpse. I see you fixed a very similar issue 5 years ago for the F-86F. This time it happens with the Ka-50. Can you please take a look? Shall this issue be reported?

Edited December 13, 2022 by Flappie

MadKreator · December 12, 2022

after 2.8 there was/is a glitch in helios related to the ka-50 device_init.lua. Almost as if something within that Lua script got moved/ renamed or changed slightly. It wouldn't allow the patches to install correctly unless that specific patch for the ka-50 was omitted. Not sure how or why any of this is the way it is, but something caused a freak out in Helios. Not sure if BlufinBima has got it sorted out yet. Could be fixed in the next helios release. Might be related to this issue somehow. Most definitely sounds like ED made a behind the scene change and Helios needs to be updated accordingly.

Edited December 12, 2022 by MadKreator

xfirf · December 13, 2022

Thank you @Flappie,

I´ve forwarded your infos to the devs.

MadKreator · December 13, 2022

Helios new version released this morning vs1.6.55. The ka-50 patch issue was fixed, might be worth the update and a profile re-install to see if the issues were linked somehow.

DD_wingflyr · December 13, 2022

That is Awesome news, I was also having the Ka50 DCS crash. Helios hiccup. I was waiting patiently for this update Thanks you Guys you're the best.

xfirf · December 13, 2022

For me this did not fix the mentioned issue.

xfirf · December 14, 2022

Hey @cofcorpse Is there any chance you can have a look at this one?

BluFinBima · December 16, 2022

Unfortunately, Helios 1.6.5500 was never going to resolve this problem. Unless ED can explain how Helios' use of the update_arguments() on GetDevices(0) was incorrect, then this isn't something which Helios can resolve. Hopefully cofcorpse will work his magic on this issue (which was also reported on the new MB-339).
