Update: Still unable to consistently play Arma 3 on my computer. Is there any other support you may provide, or is this just not a problem you can fix at this time. I have tried everything from different memory allocators to different ingame settings nothing appears to make a difference.

I switched branches and tested the game on multiple single player missions with no mods, the game was stable. However single player is not where I am experiencing problems, so I have switched back to the current version so I can continue to play multiplayer on servers that don't have 1.64 . While searching through my local appdata I found a multitude of crash dump files from Arma 3. These are incidents where a crash occurs while attempting to add mods to the launcher from my local files, I am unsure if these incidents are related to the bigger issue but just in case here are the files.

Here is a dropbox folder with three recent incidents including all the files left behind. All I am getting is a .rpt file and a bidmp. https://www.dropbox.com/sh/y608x6p8ia0njm8/AAAAvgEHouWG9wh1xxFAMMEPa?dl=0

The issue persists and every time I attempt to gather the info you need the game crashes before I can retrieve it.

That's no problem at all, naturally I will have to wait till the error occurs again. Is it safe to run Arma in profiling branch for an extended period of time with mods on? I play Arma almost daily in a community and if I could run it in profiling I will just enter frame when the error occurs again. If this is possible it may take me a couple of days to get back to you as the error occurs only occasionally.

Apologies for the lack of response, I was out of town. I have followed the steps again and I believe I was able to retrieve the info you asked for.

I attempted to take the steps that you provided. When I press Shift + Num - and enter "frame" nothing appears to happen. I have attempted to take the steps in multiplayer, singleplayer and editor. In the meantime here are the remaining rpt files and the mdmp file you requested.

Including 2 .rpt files both relative to time of most recent incident. Using mods at the time.
