I just tried quixel and imported a bunch of plants, but no crash.

Could you give me a walkthrough to create the crash?

If you have less than 8gb of ram or if you importing a lot of plants at 1 time, you'll need in import. Save and restart Unreal because the shader compile process sucks up a ton of ram. Then if you don't have enough for out of core.....crash. I have scenes with 20+ different plants and over a few hundred to a thousands on a RTX 2080 with little to no issue.
