I see others have had this problem, too, but comments have been blocked for some reason. Maybe because there's no solution yet? But every time I open the Sonos app if I have music playing the volume shoots up to 100%. I don't touch any buttons or sliders or anything, it does it all on its own.

Since you can easily recreate the issue every time you open the app, submit a diagnostic and contact Sonos Suppprt to discuss the issue.
In the meantime, I would set a volume limit on the impacted speakers.
