Character BP not working after a crash

Hello, first of all sorry I don’t know where to post this but I really need help…
A bug broke my main character and I kind of lost hundreds hours of work.

Here is what happened :

I wanted to implement some Camera Shakes in my project to add some visual feedbacks.
I created a camera shake legacy and added it to my character BP.
I already made it in a previous project so I closed my current project and opened the old one to check the settings I made since I liked it.
UE crashed when I launched a test map I had in here.
I reopened the project, just checked the camera shake settings I’ve made, then closed it.

When I opened my actual project back, my Character’s BP wasn’t working anymore, at all.
My base skeletal mesh isn’t showing anymore and the details widow is bugged.
My movements code (that are not linked to my skeletal mesh to work) isn’t working as well and I get critical errors everywhere.

Before opening the BP I see the character as it should be in the thumbnail.

Does anyone have any idea on how it happened ?
I’m working on 5.3.2 version, and already tried to verify it.
The previous project I opened wich crashed was on 5.4.
I didn’t saved anything in both of the projects for the bug to happen.

Again I’m sorry if i’m posting in the wrong section.
I really need help…

Thank you very much if you at least try to help me.

If your Character BP does not work after a crash, first check for errors or missing references in your Blueprint. Make sure all assets and components are linked correctly and that the crash did not corrupt your files. Additionally, check if the crash is caused by a specific function or event in your Blueprint and test it with a simplified setup to isolate the issue. Finally, consider restoring from a backup if possible to resolve potential data corruption.

Thank you for your answer !
Unfortunately I tried everything at this point, the only thing that seems corrupted is my character’s body SM but I can’t interract with it anymore, and nothing works, even components unrelated to it.

I thought it was maybe a known bug with a simple solution, sometimes I’m too optimistic :slight_smile:

I’ll try to create a new BP today, readding the components, copying the code and recreating the variables.
I’ll see step by step if I can reproduce the bug, or if it was a random corrupt.

I think it is time to learn everything about backups as well.

Thanks for taking some time to answer me,
Have a nice day
