Blueprint Error Crashes Editor

Hi,
When i edit my blueprint, editor crash suddenly, then every time i try to open the project it crash all the time.
I try to move the Content folder out after that i can start project like normal, then i put back the Content folder, all the resource seem normal except the blueprint i edited.
I try to open it, it’s say the parent class have been removed, then i restart the project the crash happen again.
Is there any way i can recover the blueprint or fix this problem without delete the blueprint i made ??

Yes, i have but it’s only have 1 .umap file inside

Hello Duncan,

It sounds as if the Blueprint may have been corrupted.

Is there a Backup of the asset in the following folder that you can recover: Unreal Projects\Project_Name\Saved\Backup

-W

Do you happen to recall what you were doing in the Blueprint prior to it crashing so that we can attempt to reproduce it?

I try to create and add event dispatcher for my character blueprint, then editor just freeze then crash.

I have the same problen. My backup folder has around 800+ files. I tried to replace all files i have backups from with the latest backup files but the editor still crashes.link text

this is not the full log. After that only follows a stack trace that is too long for the log so it gets truncated
