Total War Warhammer III crashing constantly. Any advice for a not-super-techy person?

What solutions do people have for the game just crashing out to Windows whenever I try to start a campaign? This hasn't always been the case and I was able to play about 5 hours before the constant crashing happened. I don't have the best PC in the world but I should be able to play the game according to System Requirements Lab (but i don't know how reliable they are). Graphics card drivers are up to date and the PC has been restarted multiple times. PC specs below. Any help would be greatly appreciated.

Video Card: NVIDIA GeForce RTX 2060 SUPER
CPU: AMD Ryzen 5 3600 6-Core Processor
RAM: 16 GB
OS: Windows 10
