Frequent Crashes Occuring With 4.18

Since the new update, my game is always crashing and freezing randomly, even on the packaged version. I have no Idea why it occurs, I tried to turn off Dynamic Instances Buffer for my dynamic foliage because I have read that it is unstable at the moment, but it did not change anything.

Have you solved it?
Same Here. Not crashes in my case but, suddenly, freezing constantly each 3/5 second. In fact. I cannot work on my projects this way anymore.(4.18.3)

Please, any solution!?

It seems like the problem have been solved by itself, I don’t know how.

yes, It´s now fixed some how.
