ue4 low level fatal error 3971 after new update

[Electrician™]

Anyone getting this? ue4 low level fatal error 3971 after new update. Any solution?

Not only delete the mods folder but completely delete the game folder where Steam installed the game and let Steam create the game folder afresh and download into it. That resolved my issue. Hopefully that works for you.

First I saw it was today as well. Were you able to resolve it? I don't use any mods for the game if that helps. Have you had a chance to dig on it at all? I have the infamous EXCEPTION_ACCESS_VIOLATION reading address 0xffffffffffffffff error. Looks like with other UE4 titles, this is pretty common.

Glad to hear it. I am still seeing the issue, but what is odd, is that it only does it if I go crazy with the brown thunder mission. Lots of rockets in Los Santos seems to freak the game out, not sure why yet, still trying to dig.

Hey, just to follow-up. Still not sure what is causing it, but I can confirm that another PC that I have tested on crashes the same way, and with the same memory address. Thinking the game is just bugged. In both cases, they were fresh installs, no mods. Also could be settings, the same settings were used on both systems. Maybe one particular is bad. I did try disabling City glow, but that didn't help. No render scaling was used(DLSS/FSR). Also tried DX12 and even DXVK, doesn't seem to make a difference.

Just to chime in here... I get the FATAL ERROR in Vice City DE - Wild thing is, if I don't move at all, no crash. After running around after like 20-30 seconds, the game crashes with the FATAL ERROR.

Error doesn't occur in GTA 3 DE or SA DE.

Have you had a chance to look at the crash log? Should be within the rockstar games folder in your documents folder. Each game has its own subfolder, at which point as you dig, there should be a crash folder. Wondering if you are seeing something similar, despite not having issues with SA or III.

In the VC DE Crashes folder, I see multiple folders created each containing an INI, DMP and XML file. I don't know what to do with these files or how to open them, really.

[Sam]

Open the XML file with notepad, the crash error will be near the top. On my end, it is the 10 line down from top.

Mine:
<ErrorMessage>Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0xffffffffffffffff</ErrorMessage>

[The Dark Knight]

10th line:

<ErrorMessage>Unhandled Exception: EXCEPTION_ACCESS_VIOLATION writing address 0x0000000000000040</ErrorMessage>

When the game crashes, it does say FATAL ERROR. Interesting to see this now. More info the better. I've even tried reverting back to a previous NVIDIA driver but no help at all.

Okay, so far, are these the only games that you have issues with? Your address looks more normal, compared to mine. Might want to check another crash to see if the address is the same. In my case, it is the same for all crashes on both PC tested. If your address changes, might want to test your RAM, just to be sure. I am sure the games are just bugged though.

Yeah, this is the only title where I am getting a lock-up/crash, to be real honest here.

Just checked roughly 10 crash XML files, all the same addy listed. I am going to GOOGLE this error and see what else comes up. I'll mess with the RAM test as well.

A part of me wants to uninstall game on Steam and install via the RS launcher, see if there's any difference.

If you are able to download via RSG, it might be a good idea. Because it is the same address on each error, probably the game. Usually, when you have RAM issues, the addresses are all over the place. Also, more common are BSODs if the user actually has bad RAM.

On a side note, when I googled my error, not a whole lot came up, hope you are more lucky though.
