It could be, but it’s hard to diagnose these things.
Unlike @Xevyr, I’m not a modder, so I can’t figure out which of the messages in the log are a cause for concern and which are just the result of spaghetti blueprint coding that is ubiquitous when working with a visual PL.
However, I did manage to find 3 other reports of the same issue. Only one of them is mod-related, but it does happen to be about the IQoL mod.
The other two reports are about the issue happening in the base game, without any mods. One was reported by @KorgFoehammer in November of 2023 and has a script stack similar, but not identical to the one in your log. The other was reported in 2020, has the identical script stack in the log, and also occurs on a computer with only 8GB of RAM.
Here are some ideas to try to narrow this down:
- Is the game minimized when the crash happens? If it doesn’t, we can discard @KorgFoehammer’s hypothesis.
- Can you try playing without the IQoL mod? Make sure to make a backup of your game database, just in case removing the mod causes corruption.
If neither of those helps solve the problem, I would suggest getting more RAM for your machine, or at least running the game on a machine with more RAM to see if that solves the problem before deciding to spend money on more memory.
