(Possible) Memory leaks resulting in client crashes

[No workaround or official answer regarding this issue so far]

I've been recently following some issues regarding to game crashes.

These issues had users having their client crash responding with an error indicating that the client was trying to allocate terabytes of memory.

(This is an indication of a memory leak)

Now clients are crashing without producing this error directly, possibly in some instances freezing the entire computer due to said issue.

We've received some .dmp files from users encountering this error, I've attatched them to this post.

After analyzing these files, it seems like the application is attempting to write or read an invalid memory address.

With recent issues related to memory leaks, I assumed that this would most likely be related to that.

This is something that cannot be resolved on the user's side, so it's definitely an issue related to the code.

Here is an Analyzed .dmp file:

    I thought Denuvo is used as copyright protection tool but Apex is free to play. Does Apex use it against hacking?

    Some people on Reddit were able to fix it by disabling/removing unverified drivers from windows. That fix did not work for me but I only had one unverified driver anyways. Haven't tried disabling other drivers so far.

    @Tavaro Denuvo is also partially used as anticheat software, though this information might just be a fluke from another error.

    I've also had some users use Linux and open-source drivers, hasn't resolved their issues.

    I'm getting the feeling that many issues like this seem to be related but might be completely different... that would be very bad.

    We just need people from the dev team to analyze these .dmp files, they have the debug symbols which we lack.

    It's most likely not even a memory leak anymore, it's just whack.

    Still no fix. Still no feedback from Respawn. Very annoying!

    I installed Windows on another Drive and there apex works. But I wont reinstall my main windows to play apex. Very annoying!

    @Tavaro I was one that faced the trouble exactly same as you're on;

    same windbg error code, addresses, etc.

    In my case, some driver that is "hated" by new anti-cheat system was a cause.

    (It was Ctrl2Cap.sys, just in my case)

    I resolved it by following:

    1. Install Varolant(I'm not joking)

    2. When Riot Vanguard (bundled with varolant) launches, it complains if there's a driver or some that "violates".

      (It was Ctrl2Cap.sys in my case)

    3. Uninstall the driver by certain procedure and of course, reboot the machine

    try it if you're still out of outlands.

    Thanks for the tip but Valorant is working fine. Its just apex. Still broken. I already tried removing all drivers.

    @Tavaro Could you try disabling any XMP profiles you have enabled?

    Seems to be the cause for some users.

    I've been looking in multiple threads and have seen you in trying to help, I immensely appreciate this. I've always had issues with Apex crashing every few seasons. When this would happen, Respawn would eventually put out a hotfix to fix this. This season, though, it's the worst it's ever been. It's been crashing pretty much once every two games, sometimes twice in one match. Before I thought it was an issue with my processor getting hot, so I reapplied the thermal paste and bought a new, nice fan. This season, I figured it was an AMD thing with faulty drivers, and bit the bullet, spending $700 on a new GTX 3070, not only upgrading my Radeon 5600 XT, but switching over to a NVIDIA altogether. This STILL hasn't fixed my issue. I've reinstalled the game, deleted the saved games folder as someone had suggest in another thread, updated .NET framework, updated my Intel chipset drivers, etc. I for the LIFE of me cannot figure out what is going on and I'm getting INSANELY frustrated. As you probably assumed, I'm getting the SAME exact error in the crash logs: SOFTWARE_NX_FAULT_AVRF_c0000005_r5apex.exe!Unknown

    How do we get Respawn to acknowledge this issue? I know there wasn't ever an issue with my system, because this is the ONLY GAME this happens in. Everything else runs smooth as butter.

    As I already mentioned I installed a fresh windows onto another hard drive and with that apex works fine. So it cannot be anything related to my hardware. Its just a software problem. And it all began with the

    denuvo anti cheat update.
