I tried to open a class in Xcode. I quickly noticed that autocomplete isn’t working. Later I found out that it could be due to my disk name with spaces which my unreal installation is on. I renamed the disk, reinstalled unreal and removed all of the cache. Every thing in unreal itself seems to be working fine except for this.
This is the exact message in the Xcode console log:
LogCsvProfiler: Display: Metadata set : systemresolution.resx=“1280”
LogCsvProfiler: Display: Metadata set : systemresolution.resy=“720”
[UE] Assertion failed: U_SUCCESS(ICUStatus) [File:./Runtime/Core/Private/Internationalization/ICUInternationalization.cpp] [Line: 162]
Failed to open ICUInternationalization data file, missing or corrupt?
Message from debugger: killed
I run macOS 26, and have an m4 chip.
Unreal Version: 5.7.2
Xcode version: 26.2
Any help is appreciated.
