It appears that a comment in my string catalog file causes Xcode to crash when it is rendered in the Source Control Navigator View (yes – it did drive me crazy)

The string is:
"X" : { "comment" : "Represents doubled in headernfrom contract struct",

which was derived from this source code:
return String(localized: "X", comment: "Represents doubled in the header")

I suspect the carriage return in the comment is the problem, but I can’t remove it.
Clearly, this comment is legacy and no longer matches the swiftui source code, but it won’t update so my Xcode crashes when trying to submit.

How can I change this comment in the String catalogue?

I tried editing the json file directly but this is ignored. I tried removing the code line and then reading it but the offending comment returns to the string catalog so I guess it’s cached somewhere. I tried cleaning the build folder and repeating the above steps – no success, the comment remains and Xcode crashes.

Can I simply drag and drop a duplicate of the string catalog into my project (with the comment corrected) or will that mess up the project?
