solved DCS 2.9.2.49629 Open Beta update Multiplayer server crash

[Ronin_Gaijin]

Hello team,

I updated to the latest OB version and DCS is crashing every time I log onto an MP server. (Tried 5 servers)
Tried to see if single player works and it does.
Changed the Export.lua file to Export.lua.bak, to fix the issue, but it did not work.
I have done no changes to DCS since before the update and yesterday it was working fine.
I also tried a full repair but it did not help.
Here are my error logs.
 

Let me know.
Thanks.

Having the same issue. single player works fine, multiplayer crashes during loading.

System: Alienware M18-r1 (64gb memory, static pagefile, RTC 4090 laptop GPU, HTC Vive Pro 2 VR headset.) Worked fine yesterday. issues came with the 12/19 patch.

UPDATE: after renaming my saved games folder and starting the game with a clean one (which should have been one of my first troubleshooting steps) the game now launches without issue into multiplayer. I must have a bad mod or mods, not sure which one(s) yet.

Are you running any mods?  There are a number of mods that will need to be updated as they are causing issues with the latest patch.

I see what you are saying, but I don't understand how I could fly in SP and not MP.
The servers I am connecting to do not have mods either.

Unfortunately it doesn't have to make sense.  Reality is that mods can have weird and unexpected impacts even on triggers in specific missions if you want to go down to that level.  There are a number of reports on the forums about mods causing issues/crashes with the current update.

Ok i removed all mods i had and i could enter multiplayer..

 

I will begining adding mods one by one until i find the culprit

I've mentioned in another thread as well. Using mods hurry-scurry is by far the most unwanted way to play DCS. Use OvGME and create profiles. Use limited specific set of mods and try as much as possible to not mix to many authors into one ovgme profile...

It is important to remove user mods before updating. 

We can not test user mods internally and we have no idea if any will break, so its best to update and test dcs in a vanilla state then add your user mods again. 

Mod creators will need check their own mods for required changes. 

thank you

Ok in my case the culprit was the JAS39 Grippen mod..

 

I added all mods back one by one and MP worked fine except when adding the JAS39 mod...

thanks for taking the time to work this out

EDIT:

Just tried this and still crashed upon connecting to a server, so for me at least other mods might not be playing well with the new patch

I've disabled all mods
performed a thorough DCS repair
deleted all mission scripts.

the only way I found was to remove a lot of blue SAMs on the Syria map (Patriot, Hawk, Manpad)

I think the last patch has a huge loss of performance on the SAMs and/or the Syria map.

EDIT:

after extensive research, windows 10 was the culprit.
It was an old win10 that had been transferred from SSD to SSD.
A formatC: solved the problem.

Bignewy and all those who chimed in, removing my mods helped with logging on MP servers again.
Now I will add my mods one by one to find out where the problem is.
Thanks once again!

Let us know which mod is creating the issue, it will help others. 

thanks

Also in my case it was the JAS39 mod (latest release 1.8.5).
