Unable to post in support, trying my luck here.
EDIT:
Yeah, it worked. Support forum keeps saying "invalid captcha" while providing not captcha to write.
I experience frequent CTD in my late games. So far my third game since I bought the expansions and it fits a similar pattern:
The game is stable until very late in the game when I have researched most of the tech tree and I go on a conquest spree. The first few planet conquests happen without notable incidents. As soon as I start accumulating victories, conquering starbases, spheres, nexus, planets, destroying fleets, invariably, when I'm about to engage combat again against a planet or a fleet, or if I'm simply about moving one of my fleets around there will be a CTD.
Since they are so random, I don't have a save just prior to the incident.
Reloading a new game delays the problem further, I can play for a while longer until it happens again.
This folder should contain everything, hopefully.
The latest save might help reproduce the problem after some turns, maybe.
Also, in one of the saves ("...about to crash"), I experience severe slowdowns. I notice that my CPU (7800X3D) is running at 100% on all cores at this time for the duration of the slowdown, then it comes back to normal usage.
I have attached the save games, debug info, custom factions & ship styles. I am uncertain I was playing with mods, I did not put them in the files.

These CTDs stopped once I eliminated the 2 of the last 3 remaining civilizations from my game, then all I had to deal with where the slowdowns. They did not stopped once I cornered the AI in a remote cluster through influence, but it happened less frequently. It happens during my own turn as well as during the AI's turn, like for example, if I am "gifted" new ships by an ideology and I want to move them/delete them, the CPU jumps to 100% usage then, like it has to recalculate lots of things at once.
Unexpected behavior, imho. Could be related to the CTDs I was experiencing, could be not. I've left everything in the folder.
