After importing my project from Unreal engine 5.2 into unreal engine 5.3 I get an error in player controller and main character class while loading the project. The message says:
“Failed to find script package for import object ‘Package /Script/InputBlueprintNodes’”
When I open the blueprints with errors all the enhanced input action event nodes have been deleted. If I recreate them everything works as it should, but if I close and open the editor again (compiling and saving the blueprints before closing), then all the enhanced input action events are deleted again. these are the events that control player movement, trigger jumps etc.
Has anyone else experienced this? Is there a fix for it or a bug report somewhere?
In 5.2 works fine, it is when I open the project and convert it to 5.3.1 when this errors start to happen.
There is a reddit post on the issue:

My brain tells me to move away from blueprint as soon as possible. Searching in the UE source code the LOG that prints the warning message I am having only appears in one place. Why is it not detecting the package if the files are present?
UPDATE: I reproduced the error in a brand new default 3rd person project. Just select C++, create the project and try to add IA_ nodes to default 3rd person character blueprint main event graph.
Save exit and then on next start the nodes are deleted. I will file another bug report with the steps to reproduce and the project.
Seriously epic, this is “production ready”???
