animation file currupt

So i am new to unreal and i came across this problem where the animation blueprint file wont open and says file corrupt and when i try to move into content browser from file explorer it says unknow asset.

This animation Blueprint file works only on the original project which i downloaded to learn replicating it tried migrating the file from the original project as well as copy paste it idk how to solve this issue can someone help me

what ver of engine are you migrating to which?

same version 5.4 to 5.4

could you perhaps check .uproject filed of original project and see what plugins they have enebaled and compare with tours, its weird migrating and also direct copying gives you corrupted file, also you could try to Validate that file/folder where that assets is. Sorry no other ideas atm.
