Why does Unity crash on DX12?

Hello! I use Unity 2018.2 and It runs with DX11. I hoped Unity runs with DX12. So I tried Unity running with DX12 many times. But, It always crashed. I couldn’t search how to resolve the problem.
Could you teach me why Unity crash and how to resolve?
I am sorry for my poor English. Thank you!

p.s. My computer’s specification
CPU : RYZEN5 2600
GPU : RX580
RAM : DDR4 2400MHz 16GB
Unity 2018.2.15

Man i have the same problem even in the newest editor. BRuuuh.

Same problem. Did you find a fix?

I have the same CPU and GPU and was running into the same crash. I fixed it by updating my GPU driver.

I am now using the Adrenalin 22.11.2 driver, and I was able to update my project to DX12 without crashing.
