iTunes audio feed kicks out at 40 minutes

[KathyL]

I am given Host duties, teaching a fitness class for 1 hour.  iTunes shared through computer on Zoom platform (latest version).  Licensed Host has unlimited meeting duration time.  For last 2 1/2 years, iTunes music streamed through Zoom beautifully without issues for the entire hour session.  Since January 2023, , the iTunes music audio stream stops at approximately 40 minutes, but the audio (microphone) and video Zoom meeting continues.  However, I am unable to restart iTunes without terminating Meeting and re-booting computer. 

Please help!  Thank you!
