so I believe I've figured this one out, this happened in my game and I searched the map several times until I noticed that a few of the cities trigger this error when they upgrade past level 5.
In my game it's the cities of Copenhagen and Juteford. I simply stopped upgrading those two cities at level 5 and haven't had the error since. If these are enemy controlled cities you want to take you simply have to raze them until they're level 5, if they have walls you have to starve them out until they go down to 5 on their own. I know it's tedious but it's the only solution i've discovered. I'm unsure if any other cities cause this error but if anyone discovers that they do i'll start a list. I hope this helps.

So I started the mod to test this and chose Copenhagen as my starting city/faction. I upgraded the city to 5+ and no crash happened. Then I conquered Juteford and also upgraded, again no crash.

Did you research any economic skill that are related to city upgrades, such as the increased supply range ones? Or have there been some special city upgrades/buildings in the cities when the crash occured?

Hi, this crash too. Have you got an email address I can send the crash dump to? I researched all of the economic upgrades. Please help. This mod is literally my favourite game and at the moment it is unplayable.

Hi, if it will stay here. The link to my crash dump from the mod is https://mega.nz/file/gyNGWLYA#ZxsT6qlcgbkOwHyUE_MCE4ibc45HU31JuvUlcC_l7Tg

I had the all tech supply range tech researched at this point, no buildings built in the cities at all just to test it. I'll see if i can get a crash log, is there any way for me to get you a copy of my save file for you to run it and see for yourself? I have also noticed on some runs its different cities that trigger the error as well

Latest crash

Is anyone looking into this still?

2 times crash today...

This can have a couple causes but my understanding is that usually it is due to a corrupted game or bad driver that needs to be updated. I would assume a chipset driver if that is the case but it could be a number of things. You can learn more about this error here.
https://learn.microsoft.com/en-us/shows/inside/c0000005

"An Access Violation is a type of Exception caused when an application Reads, Writes or Executes an invalid Memory Address."

If I read the output right it is a read violation which could also point to bad RAM. You can use this link to see how to check if you have any issues with your RAM (You should not buy their product only use the tutorial).
https://www.easeus.com/computer-instruction/windows-memory-diagnostic.html

Also, do not use any software that says they will update all your drivers for you. They all try to get your money even if they say it's free. Only software from the manufacturer should be used for drivers.

Hi, ok so I think it is sorted (Touch wood!) I reinstalled everything and so far, so good. I'll keep you posted. Checked drivers plus RAM and all ok.

Sods law... Now I'm getting this crash. Yes, definitely something to do with the memory however not faulty memory. There are some suggestions it is to do with RAM overclocking. I wonder if I need to stop using Game Booster whilst I play this but I don't know.

Thanks to all for troubleshooting this issue.

At the risk of stating the obvious, the dumps that Canute VII and markdeakin14 posted each point to the same unreadable memory address (0x000000000000002E0) that I originally encountered. I suspect that would not be the case if each of us was having some kind of RAM problem or had corrupted game files. There is something deterministic happening.

One other observation that may help with the troubleshooting: not too long before I got the crash that I reported in my original post, I got _another_ crash when I expended a skill point to extend my supply range. This was the first skill point option to extend supply range. At the time, the game was humming right along until I expended that skill point, then it instantly crashed the moment I clicked to extend supply range. Makes me wonder if Domination Station and Canute VII are on to something in suspecting some disconnect in the map file.

Now I am even more curious to learn what is causing the problem.

Thanks again, everyone!

Sounds like for some cities, when their supply range extends far enough to encompass certain point(s) on the map (either by city level or skill research), there is a crash. Perhaps someone can try narrowing down where in the map is causing the issue based on the clues from earlier posts/reports?
