FCPX I Lost my project

Hello, i m new in the forum and new in fcp x as well. I have a big problem last few hours with my project.
I had 2 stucks with my fcpx 10.2.3 and in the 2nd one i lost my project. I tried to reload my project from: file - open library - from buck up, but now it worst that previous. I am beginer with fcpx but i worked the project about 2 weeks and now i have nothing.... could you help me please? The result is in the pic No1.





My project was in folder AUSTRIA 600D, and now that folder (event) is emty. and all video files moved (i dont know how) in folder AUSTRIA TIMELAPSE 1. (Pics No2 and 3)
But i cant find the project....







The difference in my folders (events) is that the main folder AUSTRIA 600D is without the star in front of the folder (WHY?)
The original project is called AUSTRIA ALPS 2016 (Pic No4)





Someone told me to delete CurrentVersion.flexolibrary file from library bundle (right-click on the main project in my HDD, and select Show package contents)

When i deleted the CurrentVersion.flexolibrary file i lost my main folder from my project Called AUSTRIA 600D. I had there my edited project.






Also look at the folder ''Show package contents '' , there is the folder AUSTRIA 600D and if i open the foler i can see all the original files.
If i delete the CurrentVersion in folder AUSTRIA SEQ (There was the project) is there a possibility to open again the project?

The fact that there is no icon for that item (was it a Folder, or an Event? Two very different things!), tells me it somehow got corrupted. That further tells me there was a problem with your system somewhere else, first. So let's cover some basic information to help us get started. And FYI, never delete the .flexolibrary file, "move" it to some temporary location, so you an move it back if needed. I see all your media is being stored outside of the Library (links in the Original File folder, not actual files). Where are they exactly?

Mac details (RAM, GPU, model, year, etc)
Are your media and Libraries on the system drive, or external drive?
Did you run Disk Utility's First Aid on your drives first (I'd have also run Disk Warrior)?
What are the capacities of all your drives, and what percentage of each are left as free space?
Has anything changes on your systems lately (hardware software), been added, removed, any other problems?

Yeah, in this case, that .flexolibrary needs to be put back. Do you have a backup of this Library? Select the Library in the Libraries pane, go to the File menu, to Open Library, and in that sub-menu, chose From Backup.

Help please 🙏 I lost a whole library with a project I was working on 2 days ago, yesterday it was gone. Where would I find it? It does not appear anywhere even in finder.
