Warning: In asset 'None', there is an enum property of type 'EMobileShadowQuality' with an invalid value of 'PCF_2x2'

Hi
I have no idea what this is. The issue have been for awhile now since I transfer over to Unreal engine 5.0-5.1 I can export no error only warnings. But the game crash on my Samsung S20Fe

Anyone know why this might be?
