Hey I got the exact same problem, did you find how to fix it ? Thanks

Alright I just fixed it with this post : [4.18.1] Iphone launch / packaging fails with System.FormatException: Unknown char at at UnrealBuildTool.IOSExports.SupportsIconCatalog - Programming & Scripting - Unreal Engine Forums

Follow this : ‘’ Thanks for this! I’m running Win10 set to United States (under Region settings), but date/numbers format was still set to Swedish. Got this fixed by going to Control Panel\Clock, Language, and Region\Change date, time, or number formats\Additional settings\Decimal symbol and changing it from ‘,’ to ‘.’ ‘’
