Playback cursor frozen in YouTube video

Hello

I've recently been updated to the new version of MuseScore version 4.4 in the week and while converting my short compositions into YouTube videos I've noticed that the playhead does not move at all.

Before I updated MuseScore to the latest version the playhead can be seen moving along through the score but now it is just stuck at the first note after the music starts playing...

Is there a work around this perhaps?

I've attached a screenshot that shows what is happening.

The video is already at 0:16 seconds but the playhead is still stuck on the first note after the music has started playing.

Please assist...Thank you
