Hello thanks for raising this. Could we please get your save file, plus your rec file from a match where this occurred, these can be found here - C:\Users\Your Windows Username\Documents\Sports Interactive\Football Manager 2023\matches
Also, can we ask have you experienced this in just one match or multiple? If it happens in one match will it happen in the next CL match? Have you been playing for a while in one session when this happened? Did you have music and/or sound set to off or on? Thank you
