MuseSound Playback Audio Out of Sync
Steps to recreate the bug:
1. Use MuseScore 4 regular release version to create or open a random score containing at least 2 parts, such as the one I attached.
2. Install MuseSounds.
3. Make sure that all instruments use MuseSounds instead of MS Basic. In fact, using MS Basic is the only workaround that I found.
4. Click any note of your choice, and then press the Space bar or click the play button to play.
Expected behavior: When clicking play, both parts should start playing at the exact same time.
Actual behavior: When clicking play, the selected part starts to play about half a beat later than the other part, and then catches up on the next note.

In addition, I found two things. First, if the note being clicked is played by an instrument using MS basic, even though everything else is using MuseSound, this bug will not occur. Second, when all of the instruments are using MuseSound, only the part that is being clicked is delayed, and all other parts start to play together at the expected time.
