Logic Pro presets doesn't load third party plugins

Hey! I just got my 16" M4 max MacBook, did all the setup yesterday. A problem is occurring with my Logic Pro presets. It seems like none of my previously made presets are loading any of the 3rd party plugins. They are still in the chain, but blurred out, as when they are currently loading, but nothing happens. All the plugins are working if loaded separately. The MacBook was set up via Migration Assistant, from my earlier MacBook pro (2020) Is it possible, that Migration Assistant somehow messed up the routing? Or else, can please someone help what could be the problem? Thanks in advance.
