Also when Exported to a WAV audio file there is exactly the same lag as Export to MP3 audio.
Musescore Version 4.0.0, Muse Sounds, Muse Woodwind, Alto and Tenor sax Sounds
A workaround seems to be to not mix Mus Sound and MS Basic Instruments.
I substituted a Contrabassoon for the MS Basic Bass Guitar and it worked using all Mus Sound Instruments.
