NSAttributedString - Thread 1: EXC_BREAKPOINT (code=EXC_I386_BPT, subcode=0x0) when setup attributedText on iOS 14-

I have some weird problem. On my Macbook M1, when i build my project, everythink working well on physical iPhone XS 14.4 and 8 14.0.1, also on simulator with iOS 14+. But when i run any simulator with older iOS than 14.0 my app crashing when setup attributedText. Here is my code:

        guard let input = input else { return nil }

        guard let data = input.data(using: String.Encoding.unicode, allowLossyConversion: true) else { return nil  }


        if let string = try? NSAttributedString(data: data, options: [NSAttributedString.DocumentReadingOptionKey.documentType : NSAttributedString.DocumentType.html], documentAttributes: nil).string
        {
            //Set color and font
            let myAttribute = [ NSAttributedString.Key.foregroundColor: UIColor.white , NSAttributedString.Key.font: UIFont.systemFont(ofSize: 17.0)  ]
            let myAttrString = NSAttributedString(string: string, attributes: myAttribute)
            return myAttrString
        }

        return nil
    }

The crash is in this line:

        if let string = try? NSAttributedString(data: data, options: [NSAttributedString.DocumentReadingOptionKey.documentType : NSAttributedString.DocumentType.html], documentAttributes: nil).string

for NSAttributedString i got error Thread 1: EXC_BREAKPOINT (code=EXC_I386_BPT, subcode=0x0) I have try run my App on Macbook Intel, and there everythink is ok on simulators with older iOS than 14.0. So this is for me weird. Should I throw the application on the App Store anyway, because the fault lies only in the simulator or, however, the users may have a problem? I tried various solutions from the Internet, I changed the NSAttributedString modifications, but the applications always crash in the same place.
