Hello,

First, check if your Arma 3 root folder if your exported PBO file is located here.

C:\Program Files (x86)\Steam\steamapps\common\Arma 3\MPmissions

Second, chceck if your exported SQM file is located here

C:\Users\*username*\Documents\Arma 3 - Other Profiles\*profilename*\mpmissions

If you haven´t MPmissions folder there so create some one.

I´ve checked your RPT and there are many SQF file errors. These files contains content script. There must be some kind of damage so try your mission export again. There is the possibility that you have the mission duplicated somewhere.

Third, try these common possible solutions one-by-one.

Try restarting your computer and then verifying the integrity of the game cache for Arma 3.

1. Restart your computer and launch Steam
2. From the Library section, right-click on the game and select Properties from the menu.
3. Select the Local files tab and click the Verify integrity of game cache... button.
4. Steam will verify the game's files - this process may take several minutes.

Try all of the possible solutions listed on the Arma 3 Unusual process exit article on the Bohemia Interactive Community Wiki.

Try switching to and playing on the profiling game branch. After downloading new data verify the integrity of the game cache.

• profiling branch (special performance + profiling build - requires access code: CautionSpecialProfilingAndTestingBranchArma3), alternative download of needed binary possible from Dwarden's dropbox

Try to delete your profile folder (create a backup) a try to start the game.

The file yourprofilename.vars.Arma3Profile must be deleted.
Path: C:\Users\*username*\Documents\Arma 3

So, there is some next solutions.

try to decrease your graphic quality (if you're using ultra set high or medium). It´s possible that your have no more space on your GPU.
reinstall your GPU drivers

I've already done all of this.
tired all three branches.
deleted and re exported the pbo in my mpmissions.
deleted my documents folder and put my mission folder back in.
reinstalled my drivers
A lot of the RPT errors were from missions being opened earlier on,
as it somehow got dumped in the same place with the mission that caused the crash.
I looked at all of the errors, and none of them are related to the crash mission.
I've already moved the mission to a new folder and replaced everything that was contained in the mission.sqm.
So this has happened before without any obvious problems.

combat.vr
and
spawnMortar.sqf are the error lines.
Frogman.Tanoa is the mission file.
Don't see anything in there

@MidnightersHouse Try to delete this files if they are present in your folder (make backup) and get them back. Also, try to reinstal/update your. Microsoft Visual C++ 2015 Redistributable

@Alwin I'll try that.
