Late game Movement needs some help.

When ever I reach late game movement becomes a disaster. The game constantly chunks because it automatically ends my turn while I'm in the starbase menu building modules or a shipyard building ships. The game just halts and slows to a crawl. Every time it seems to be caused by the game automatically ending turn while I'm doing something. I can't complete a single turn at the late stage game. The third exception that degrades game play is Auto Save - End Of Turn automatically gets initiated during Auto Save. This game has many issues - like planet names being displayed as banners which hide the units and the overview menu not working for starbases - everything shows constant update and never clears. Then there is the problem with citizens constantly leaving and then coming right back the next turn which trashes citizen assignments. Farmers and such keep getting removed because the citizen leaves and then automatically gets replaced. Every time I reach turn 100 these issues typically cause me to start a new game because it's too tedious to continue playing. I typically can only do one action by turn 100 because End Of Turn derails the game play. Can't issue orders anymore. Another issue are the minor races. The Ideology Tree forces the player to be friendly with white units. If I don't use the console to delete them they multiply too much and start causing problems by using too much memory. Space Monsters and Red Units can be taken out and removed with my fleet so they don't accumulate and cause problems. The vast number of White Ships adds significantly to the movement problem if they are left alone.

 

For the record I have a CPU with 16 cores running at 4 GHz with 128 GB ram and a 2TB SSD. The game doesn't use my available resources. I run windows 10. My adapter is an NVIDIA GeForce RTX 3070 Ti. I should have no hardware issues with this game.
