Blueprint 'could not find function' error after close project

[Qiangpan_Chen]

After close project, the blueprint always has this error, please help

Then I had to rebuild again, via live code, or build it from VS Code, then to call the function again.

Did you compile with Unreal closed?

[Qiangpan_Chen]

I did, I closed Unreal , and went to VS Code build it with the Development Build .

Also I found if I build in VS, I cannot get the call function, they are only appear in blueprint if I build them through Unreal Live code

Are you sure you used the right task? There are 2 Win64 Development Build tasks, ProjectName and ProjectNameEditor, you want the editor one as that is the one that compiles the .dll the Unreal Editor will be loading.

Fixed by ProjectNameEditor, thank you so much !
