Hello, when I try to launch unreal engine I was get the error “Serialization Error : Action Needed Corrupt data found, please verify your installation.” After verifying the installation I still get the same error. Ive tried reinstalling unreal engine and epic games launcher multiple times but it still doesn’t fix the problem. (I’m using a mac) Thanks for any help!
