Itunes 12.7.4 doesn't launch anymore after upgrade
Hi,
Today, iTunes was upgraded to 12.7.4 and High Sierra to 10.13.4.
After the upgrade, I tried to launch iTunes, but it didn't launch anymore. The famous spinning wheel start and never ends.
Working on an 27" iMac, 2017.
My library is on a Synology station. And at the station I see that the CPU is speeding up to 100% for a certain amount of time.
Also finder stops responding after launching iTunes. Restarting the finder doesn't work, it doesn't respond after the reboot. Also rebooting the system via the Apple-menu doesn't work. A "shutdown -r now" via the Terminal works.
I have tried:
1. To delete all cache. Didn't solve the problem
2. Reinstalling iTunes 12.7.4 (it was installed before the High Sierra upgrade). That also didn't solve the problem
I launched iTunes in the Cloud on my Macbook and that didn't had an issue. After trying to connect to my music library on the Synology station, the Macbook also had the same issues as my iMac.
iMac with Retina 5K display, macOS High Sierra (10.13.4)
