Suggestion on regex improvements

The current regex won't capture the chapters for this video for example:
https://www.youtube.com/watch?v=Dorf8i6lCuk

I have written a media player that parses the text containing chapter information and displays the chapter and from my experiences I noticed that YouTube just removes the timestamps regex from the string and whatever is left is used as the chapter title after some tweaks.
For example this text in the descriptions:

#2*\+  Wh#at# is\ Re#act*00:00 sdds#
#3 First React Code 01:15sdsdd

generates the following chapters

I am currently updating my chapters capturing function to behave like above. I am thinking about removing the regex below to remove the timestamps from the string containing a chapter:
/([^a-zA-Z0-9_](?:(\d{2}):)?(\d{2}):(\d{2}))/gm (still a WIP)

Edit: I have come up with a way to extract the chapter title and its timestamp based on the experiences I made with YouTube chapters:
Qt C++ code:

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    QString str = "#2 (00:10:00) variables ✘";
    str.prepend(' ');  // force timestamp capture when they are at the beginning of the string
    QRegularExpression re("(?:[^a-zA-Z0-9_=:])((?:(\\d{1,2}):)?(\\d{1,2}):(\\d{1,2}))(?:[^a-zA-Z0-9_=:])?");
    QRegularExpression deletionRE("^[^a-zA-Z0-9!'\"_`\\[{(\\?]*|[^a-zA-Z0-9!)'\"_`}\\]\\.\\?]*$");
    QRegularExpressionMatch match = re.match(str);

    if(match.hasMatch())
    {
        qDebug() << "Match:" << match.captured(1);
        qDebug() << "Hour:" << match.captured(2);
        qDebug() << "Minute:" << match.captured(3);
        qDebug() << "Second:" << match.captured(4);

        qDebug() << "part1:" << str.mid(0, str.indexOf(match.captured(1)));
        qDebug() << "part2:" << str.mid(str.lastIndexOf(match.captured(1)) + match.captured(1).size(), str.size() - 1);
        QString part1 = str.mid(0, str.indexOf(match.captured(1)));
        QString part2 = str.mid(str.lastIndexOf(match.captured(1)) + match.captured(1).size(), str.size() - 1);

        str.remove(match.captured(1));
        part1.remove(deletionRE);
        part2.remove(deletionRE);

        QString chapterTitle;
        if(! part1.isEmpty() && ! part2.isEmpty())
        {
            chapterTitle =   part1 + "." + part2;
        }
        else
        {
            chapterTitle = part1.isEmpty() ? part2 : part1;
        }

        chapterTitle.remove(deletionRE);

        qDebug() << "Chapter Title" << chapterTitle;
    }

}

Output:

Match: "00:10:00"
Hour: "00"
Minute: "10"
Second: "00"
part1: " #2 ("
part2: ") variables ✘"
Chapter Title "2.variables"

The extractor is not saving correctly

If you notice, they extractor not catch the first chapter:

CHAPTER00=00:00:00.000
CHAPTER00NAME=Woden

And the other thing is, the time is not correct, if you also noticed, in your extractor save as:

CHAPTER0=01:02.000
CHAPTER0NAME=Heike

Should be save as:

CHAPTER01=00:01:02.000
CHAPTER01NAME=Heike

Notice the 00 before the time, in your extractor does not have the 00 before, which indicate the hour, so when importing the file, there is always an error.
