textView with exclusionPaths and video

I put photos inside a textView if there is video in the text, then I replace the video's photo with the player, the problem arose with the player, I can't understand why the player position is not correct, I noticed replaceCharacters does not work correctly, copy? .replaceCharacters (in: videoRange [i - wrong], with: "this is correct position") replaces only the first photo and copy? .replaceCharacters (in: videoRange [i - wrong], with: "+") all but with the wrong position, example how replaceCharacters work is below

extension UITextView {

    // conver range to CGRect
    func boundingRect(forCharacterRange range: NSRange) -> CGRect? {

        guard let attributedText = attributedText else { return nil }
        let textStorage = NSTextStorage(attributedString: attributedText)
        let layoutManager = NSLayoutManager()
        textStorage.addLayoutManager(layoutManager)
        let textContainer = NSTextContainer(size: intrinsicContentSize)
        textContainer.lineFragmentPadding = 0
        //layoutManager.hyphenationFactor = 1.0
        layoutManager.addTextContainer(textContainer)
        var glyphRange = NSRange()
        layoutManager.characterRange(forGlyphRange: range, actualGlyphRange: &glyphRange)
        var rect = layoutManager.boundingRect(forGlyphRange: glyphRange, in: textContainer)
        rect.size.height = self.frame.width  / 1.7
        rect.size.width = self.frame.width
        rect.origin.x = 0
        return rect

    }

    // add image and video in text
    func convertToInlineImageFormat(htmlString:String){

        let text = videoInText(htmlString: htmlString)
