Not sure about versions earlier but 5.3 source on git has it and 4.26 from Launcher has it and so does 4.27. But 5.2 and 5.3 from Epic Launcher is missing it. I came across the issue when I tried to run an iOS build from 5.3 and it crashed on launch due to missing data folder for ICU.
So I went to try the 5.3 source on my Mac and it fails to launch although does compile fine. When launching the UE5 Editor for Mac it fails on line 162 inside ICUInternationalziation with the check of the ICUStatus failing “Failed to open ICUInternationalization data file, missing or corrupt?”
I have the same error in my packaged dedicated game server (UE 5.3). Any updates?
“Failed to open ICUInternationalization data file, missing or corrupt?”
FWIW, this happens for me too, when pulling from github release branch and building on MacOS.
I wonder if it’s a working directory problem, or actual missing data?
