Norton and Big Sur causing Apple music issues

To cut a long story short my Norton Antivirus Plus has caused it so that Big Sur 11.6.4 is no longer able to sync music to my iPhone from MacBook. With Norton installed the iPhone fails to sync and it times out. Uninstall and the iPhone syncs as it should with no issues. I had to reload approx 125,000 songs before I found this out! Any ideas of a work around so I can keep my Mac protected but also still have function to sync my music library to my phone? 

I have asked this thread be moved to the Mac forum board for better exposure.
