XCode 16 beta1 and beta2 hangs whenever I try to open Localizable.xcstrings. The localization screen appears but afterwards XCode becomes unresponsive until I kill it. To make matters worse, upon restart the last window, Localizaton is reloaded, instantly causing a hang again (I need to be super quick as I have about half a second to try to click elsewhere like crazy). The same localization strings file works fine on XCode 15.4.
I tried to export all localizations in 15.4, empty the file, re-generate localization strings, re-import languages one by one in 16, starting with different languages (thinking maybe a weird exotic character causes the issue with one of the languages, this happened previously crashing XCode 15 until I found the offending character and replaced it with something else). But generally even after just adding a single language there is a serious slowdown - after adding the second one, XCode hangs again.
Note: the app in question has a lot of localizable strings - I had no issue creating a simple project with only a few strings. Just hoping a fix - I really wished the issue was fixed in beta2 but now I am a bit concerned that maybe it's a rare problem and might not get fixed as I saw no similar reports so far.
