VFX Graph suddenly broken (HDRP)

I have a game I’m working on and I’ve built a ton of visual effects for the game using VFX graph.

Today I got Discord Rich Presence working for my game, but for some reason at the same time, suddenly all of my visual effects are broken. No errors are thrown, but no particles are created anywhere. Building the game does not fix the issue. The only hint I have is one error thrown where I have an effect who has a property set through C#

My HDRP and VFX Graph versions are both up-to-date and I’m running Unity version 2020.1.2f1. Does anyone have an idea what just happened??

Reimported all my assets and they’re back, so I guess it was a Unity bug. I am very relieved. So if this happens to you go to Assets > Reimport all
