Error in opening project

Hello, while working in my Library, i had to delete a Rec in the Rec catalog. But something gone wrong and now i have the following error :

An error has occurred. See error log for more details.
Cannot invoke “String.equals(Object)” because the return value of “org.polarsys.capella.core.data.capellacore.EnumerationPropertyType.getName()” is null

Is there a way to find where is the error and correct it ( the repair command doesn’t solve the problem) ?
I have a record of my project but i will lose my last worked…

Thanks for your idea …

Hey there, did you figure this out? I was working with the requirements management plugin and was building out my structure. Now I’m getting this same error and can’t acess the contents of the project anymore to try and fix it.

No i haven’t find a solution. I have been oblige to use my last save
