Please solve the problem that only the selected track doesn't make sound

[른자노]

Even if I select a track to edit, all tracks with synths corresponding to that track won't make a sound. This phenomenon applies to exports as well and reinstalling Cakewalk won't fix it. Please help me fix this phenomenon. If you need a reference video to solve this problem, I will email it to you because the capacity is large.

The sentence may not be smooth because I used a translator.

Also, after mute all tracks, unmute that track during playback and then mute all tracks, it will sound normal, but if you stop playing and replay it, the same phenomenon will continue.
