Hello. I found workaround for similar problem.

> sourcekitten doc --single-file example.swift

Could not cast value of type 'Swift.String' (0x1f051c2b0) to 'Swift.Dictionary<Swift.String, SourceKittenFramework.SourceKitRepresentable>' (0x1ee63a878).
[1]    20033 abort      sourcekitten doc --single-file example.swift

example.swift file content:

struct T {
    private (set) var a: Int?
}

For fix problem just remove space between private and (set).

UPD: found error explanation with debugger:

extraneous whitespace between attribute name and '('; this is an error in the Swift 6 language mode

@ZGl6YXNt that's brilliant, thank you for adding this.

Apple have broken/changed the unwritten sourcekit output rules with their "educational notes" diagnostic feature, I think for now is OK to tolerate arrays of Strings. Just need to review a bit to see if there's anywhere else this could affect.
