    Hi, we encountered a serious issue with our heavy scenes (50mb). Until 2022.1 beta 8 everything was fine (5 secs loading time in editor) but starting from beta 9 and until now we can't load scenes any more (busy progress that takes 20-30 minutes and no luck, didn't tested longer ;) ). When scene is edited and prefabs are reduced by 3/4 then we can open this scene in 2min time :tada: ;) There is no specific editor.log messages. Also tested only with empty transforms (meshes removed) problem still occurs. Seems like deserialization issue maybe...

    Same, when scene contains a lot of prefabs it seems to give up. Problem occours only in beta 9 and higher. Sometimes Unity loads the scene slowly but it can take like an hour or two. In my case the problem are trees and foliage in general, there's just a lot of instanced objects that Unity can't handle anymore.
