How is your C drive free space doing? Corrupted saves are a common result of running out of disk space, but it could also be a result if the game crashing for other reasons while saving the game.
You now say the game crashed while you were in the governement tab, but your previous posts indicate that you crashed the moment you clicked on the government tab. Is there such a difference?
Also, did you ever try to reinstall updated drivers? The last dxdiag you posted did not show what was the latest driver back then, and another version has been released since then. You mentioned that you "downloaded" the driver, but did you actually install it after downloading it?
Edit: The failure to install the driver could also be caused by Dell. The drivers for your laptop should be here (you want the intel UHD/Iris Xe driver specifically, and make sure you select the correct windows version):

The driver listed by dell seems to be older than the latest version listed by intel, but it is still newer than what you had.
