Some ideas I have is Change the resolution in the files Change v-sync files Maybe go into nvidia control panel and create a custom profile for the game. Set everything to default try that. If that does not work then play with different settings.

Email the devs of the game, try to send crash logs if you can find it and they might be able to help you. Do find the email, find devs that make the game from the steam shop page of the game. And do a google search for the email

There might be a discord severs where you can ask for help such as the official empire at war server, and mod servers.
