Moving the thread to Tech Support, since lack of crash logs suggests some kind of a hardware issue.
In the meantime you can also try deleting the Documents/Paradox Interactive/Victoria 3 folder and running the game again (to rule out a corrupted shader cache or old mods). Please make sure to back up your saves before deleting the Victoria 3 folder.
Best regards
