Error while unpacking

[Butza]

Hello! Can you give me some advice on where to look? Here’s the situation: I’m making a repack for Assassin’s Creed Shadows, and there’s a file called DataPC_Japan_ext.forge that’s 26 GB. Basically, errors pop up with large files—meaning when I run it on its own, everything’s fine, but when I run the whole 135 GB bundle, it always complains that this file is corrupted. I'm using xtool:mermaid+srep+lolz. I have 32 GB of RAM. What I’ve tried: I added RAM up to 48 GB, but it didn’t help; I reset all overclocks, but that didn’t help either. In Lolz, I set it to 2, 4, and 8 threads, but nothing changed—so it’s not a RAM issue. If I split the 135 GB into 3 files, it’s fine; but if I put them all together, I get an error during extraction saying the file is corrupted.
