Help: Could not find Util "Open_File"

[CD213]

Whenever I launch the application, I get this pop up.

[22:39:27] [Reloaded] Failed to Load Reloaded-II.
Could not find Util "Open_File"

I don't really know how to resolve it, any help would be very much appreciated.

The coloured chat icon background mod was not updated for the latest version of Persona 5 Royal. You're either using that mod directly, or it's a dependency of another mod ypu have installed.
