Water system corrupted my file

Since I added a water system and reduce its scale to adapt to my landscape, UE5 crashed.
Unfortunately I saved the file with the water system in it, therefore I can no longer open the file. It crashes as soon as he finishes to open the file…
Does anyone know how to fix this issue:

First you should create a copy of your project.

Is it a c++ build? If yes try to rebuild your project by right clicking on your project file in the file explorer.

Furthermore you could try to delete Intermediate, Config and Saved folders and start the project.

Some projects don’t start anymore because the default map file or its associated gamemode is corrupted.

If nothing of this works , use your backup.

@HAF_Blade
Thank you very much for your response.
I did a copy of the project and I delete the map from content folder, I can load another map but I am missing some elements from the main map.
Is there a way to remove or unload the water zone on the outliner element from the project folder before lauching it?

I don’t think so.
