@hitagi Disable all your mods (both in the client > Mods tab > Manage Active Mods & also in the in-game lobby > Mods). Then play a game without those mods enabled. If you get another crash, then we'll know that there's a problem with the base FAF game.
If the issue isn't replicated when playing with all mods off, then that means you have a mod that's causing the issue & you need to troubleshoot to determine which one it is. The best method is to enable only 1 or 2 mods & play a game to test if you have another crash. If not, then enable another 1 or 2 mods & play another test game. Continue this until you replicate the crash.
Once you've determined which mod is the culprit, then you'll need to go to the Modding & Tools area of the FAF Forums & find the thread for the mod you're having an issue with. Make a post in that thread reporting the issue along with your most recent game_21xxxxxx.log so the creator/maintainer of the mod can look into it.
