No Enemy Damage After UE_5.4 Update

Hello,

I have used UE_5.3 with PaperZD. to create a game. The game is working in UE_5.1, UE_5.2 and UE_5.3. I backed up the project folder and installed UE_5.4.

I can load the project up, I press play to play the game every thing works as it did in the previous versions except now my player character cannot deal damage to any of the enemy’s anymore. I have replaced the enemy actors, I have replaced the newmeshboundry areas but all to no avail.

When i installed my new UE_5.4 i did have to reinstall PaperZD but everything else works.

No settings have changed. Can anyone tell me if i have missed something obvious or if this is a bug?

Thank you
