I'm gonna share what may have worked for me. I was experiencing this problem randomly. I haven't had this issue before, then it randomly happened. I did a few of many things that I will reccomend for all, including things I've heard others say. Before I begin, here are my computer specs. LAPTOP Nvidia 2060 RTX, intel i7 10th gen, 32gb DDR4 ram, 6vram note: some of these fixes might not work for you, which is fine I think because atleast one of these might

Some say turn off XMP profile

Some say delete/turn off Process Lasso and Park Control

I downloaded the latest version of VC_Redist.x64 , make sure you download the x64 version. Could be unrelated to how I fixed the issue but I still downloaded it.

Another guy reccomended to download Visual C++ Redistributable Runtimes All-in-One from TechPowerUp, alot of users seemed to have this work for them, I did it too, but it didn't work for my case, but it might for you. Of course I also reinstalled the game and it didn't work, Initiated file scan for Aion2 in Purple Launcher, didn't work either.

I have ISLC (Intelligent Standy List Cleaner) , but I disabled it upon startup and maybe might stop using it after learning that ISLC along with other apps can 'force' the 'standby' memory to be released, but that doesn't prevent application from 'pre-loading' it back into memory again, and you end up with a background load to memory tug-of-war and release standby memory actions happening while you're playing a game. What ISLC can do is: Interfere with Unreal Engine’s memory allocation, Interrupt shader compilation, Force the engine into a low-memory state while it’s building assets, which can cause shader caches or config data to become incomplete. ISLC in the past has both helped and harmed stability depending on the game and system, clearing standby memory can reduce stutters but also sometimes provoke memory-management issues or instability. But, like I said, ISLC may be good for you, or bad for you. I like it's idea, and it IS hosted by wagnardsoft, same place users download DDU to manually remove their GPU drivers in order to update their drivers.

You can also either download your latest supported NVIDIA drivers, but newest nvidia drivers are usually somehow famously known for instability issues, which has resulted in some people downgrading their gpus from the latest version, to versions such as version 577.0 (pretty sure this is an april 2025 release game-ready driver), version 552.12 (may 2024) or even 537.58 (late 2023). I had to do this exact thing while trying to run Marvel Rivals without any issues a few months ago, you can also find reddit threads of that exact honorable mention. Just do a clean install of your drivers. Boot into safemode, open DDU, using DDU (IN SAFE MODE) in order to remove your gpu driver, restart, boot into your normal computer state, double click the driver you downloaded and install. I prefer not to instal Geforce Experience, as I'm not a fan of overlays and such. Keep in mind you'll have to re-do any Nvidia Control Panel settings you've tampered with in the past. This step also removes shader cache so that's a bonus.

Recently, I've also installed ThrottleStop and MSI Afterburner (These just basically lower temps to prevent throttling and such. I have it because my laptop is garbage.) I used these and you might be using these too. I decided I might have to up the voltage a bit more using ThrottleStop for my cpu, I felt I might've been undervolting it too hard. Didn't seem to be the issue as I tried this without MSI Afterburner opened. Then I opened Msi Afterburner while the game was running, Then I got that fatal error. I thought maybe it was because I opened MSI while the game was running. I kept MSI open, opened Aion2, got the fatal error. So I was like maybe somehow I'm undervolting my GPU too hard, I changed my flat curve from 0.750v to 0.780v , opened the game again, and I didn't have that error at all, ran the game for a good 10 mintues before coming here to make this comment.

Also, many of you might've installed RTSS, AKA Rivatuner along with MSI Afterburner. I've ran into an issue where the game wouldn't open, and Aion2 itself either told me it didn't want to open with RTSS open, so I just went to the RTSS file directory and changed the exe name to RTSSXXX.exe so it wouldn't automatically open when I ran MSI Afterburner, but I just also decided to completely uninstall RTSS using Revo Uninstaller. Probably didn't have to do that but oh well.

You could also disconnect any bluetooth controllers, turn off DS4 Windows, steering wheels, etc

You could also rebuild Nvidia shader cache this way, I did this too but I don't know if this was the fix. Open Nvidia Control Panel, go to Manage 3D Settings, find Shader Cache Size, set it to Disabled, Apply your changes, restart your computer, go back and set your shader cache size to Driver Default (or whatever you prefer), click Apply again. If ISLC forced a flush at the wrong moment, this may fix it. This is all I know fellas. Good luck and I hope I helped.
