Could you check if it still happens using a recent Winrar or 7zip? I've seen the windows zip system break at files > 4.2GB.
I found out!
While I was investigating, I started to think about the possibility that my system language was causing some kind of incompatibility. Not that there is a causal correlation, but based on my theory, I started exploring the game settings in search of some specific language and text parameter. Apparently, keeping the TTS option enabled causes the problem. Just disable it for everything to work normally.
I haven't tested it to the limit yet, but it seems to be fine!
Honestly, at this point I was driven by curiosity about the problem and forgot about the game behind all this. It's like finding money in your jeans pocket!
