Blueprint is not compatible with the current engine version

Development Programming & Scripting Blueprint

Hi

I encountered a very weird problem, I am using the Unreal engine source code, I used some blueprints too which are placed in the Marketplace folder.
all these things were working correctly.

But from two days ago, it started to report warning/error message that the blueprint is not compatible with the current engine version when I was trying to open the project.

Some message are as below:

LogPluginManager: Warning: Plugin ‘BlueprintJson’ is not compatible with the current engine version (4.25.0)
Message dialog closed, result: Yes, title: ‘BlueprintJson’ is Incompatible, text: The ‘BlueprintJson’ plugin was designed for build 4.25.0. Attempt to load it anyway?

LogPluginManager: Warning: Plugin ‘BlueprintJson’ is not compatible with the current engine version (4.25.0)
LogPluginManager: Display: Skipping load of ‘BlueprintJson’.

And due to this “issue”, and project can not be cooked properly, as the blueprint is skip to load.

I tried to remove the blueprint and add them back from the UE4 binary build, the issue is still there…

Does anyone have clue on this? Any suggestion is very appreciated.

Thanks.

Don’t know about your particular issue, but I had something similar. Some nodes are missing in 4.26 comparing to 4.25. I had created a blueprint utility that would automatically align actors in levels, but it doesn’t work in 4.26 anymore.
