Long Delay then Crash at Mission Start Point

[Bashibazouk]

My DCS takes an inordinate amount of time to start, and the problem I have with the campaign may be related to this. I've removed all mods, deleted the two folders suggested in other posts (fxo and metashaders2), repaired my build (using the shortest option) but I still have this problem, currently only with the Arctic Thunder campaign.

I start the mission (from mission 2, mission 1, the passive one, is fine), get the mission review box, click start and then wait for maybe a minute or two, and the mission starts up with me in the cockpit. This is usually the screen with the final step to start a mission and where I get the largest delays in missions that do work. With Arctic Thunder F-16, I hear the theme music play with the screen still frozen. Then nothing, until, a ridiculous amount of time later (5-10 minutes?) DCS crashes.

I've done a rebuild, all the stuff usually suggested. And this is with zero third party mods, I should add. 

The reason I've put my problem here is this campaign is the only one I cannot play at all, all the others I have do start, eventually. And I was wondering if whatever allows the music to play before the mission is setup might be intefering with my long start problem. This is a nice feature, the music, but not something I have in any other campaign.

Any suggestions or anyone else having this problem, even if you don't know why, please let me know.

 

Thanks for your time.

clarify that I'm not blaming the music for the problem, just that it might be interacting with it in a more catastrophic way

In complex missions the game needs to load more than in more simple ones. But it shouldn't crash. Please send the crashlog to ED to see what's causing it.

Also, try loading a simple mission on the Kola map, and THEN try to load an Arctic Thunder mission.
