Does not seems its any mod related, could be hardware issue. But make sure you have no conflciting mods activated. Best is to start just with our 4 required parts.

Hey Radious, thanks for the reply, I highly doubt it is a hardware issue since this is an excellent gaming laptop, and it never had any problems before. The only possibility is the combination of mods I might be using causing these crashes.

Here are the mods according to my list and the current situation:
-Faction UI overhall, has yellow marker on mod list, but exists in-game
-Faction party colours, has green marker
-Battle camera V 2.20 for patch 20, green
-Campaign camera for patch 20, green
-Better font, green
-Wrath of Sparta Campaign faction unlock, green
-Traits talents and toadies, Character overhaul, green
-Better Water III HD, green
-Dresden's sack, liberation and diplomatic options mod, green
-A bit informative unit stat box. green
-Etruscan accent in the grand campaign, green
-Pikemen start battles with pikes, green
-Unique trait icons, green
-Rome:Total War Music, yellow marker, but always worked
-Nordo's faction unlocker, green
-All four parts of Radious anniversary mod, green
-Classic battle graphics, green
-Rise of the republic all factions playable, green
-Universal Diplomacy, green
-And finally a suspicious mod called Radious_factions_playable pack left from old times but for years was impossible to remove since even if I unsubscribed from it it remained still in the mods list with neither a green or yellow marker but a blue folder icon, so far never noticed any problems with so it just remained.

Final note, when starting game on launcher, these mods are so far always disabled and have to always re-activate them manually every time I open launcher. I experience a similar problem with the radious mod for Attila.
-Dresden's sack, liberation and diplomatic options mod
-A bit informative unit stat box
-Radious_factions_playable pack
-Classic battle graphics
-Universal Diplomacy

So far I never had much issue with any of the mods, all seems to work well except the crashes. Even though some mods seem to cover similar things they never seemed to interfere much with each other and I just left them there since often modders do not fully explain details about their mods and its often confusing what they cover, including cases with radious. For example Dresden's Diplomatic mod and Universal Diplomacy mod sound extremely similar, and always had suspicions over Nordo's faction unlocker since it always seemed the only way to unlock all factions on Radious despite the fact that that so far I do not think I noticed Radious mod ever unlocking any factions whatsoever even though there are radious mods within the four parts which heavily expand custom unit roosters for factions but at the same time doesn't even unlock them.
Total number of mods is 23.
