Action RPG Inventory System

Urgent, reply requested re ARPG bug , The ‘initialise player’ event when linked to begin play, in the inventory player controller seems to crash 4.19.2 Game breaking bug, needs a fix asap.
happens when migrating 4.18 into 4.19 , or using launcher itself to update prject to 4.19. Can confirm by deleting initialise player it works fine, so its not the rest of the project. Can you put a fix, or at least screengrab of a version of initialise player thwt works in 4.19.2 and i will simply delete old initliase player BP nodes and recreate from you screengrab.
Needs urgent fix asap as is holding up a project
