VMWare workstation version: 15.0.2 (unlocked use macOS Unlocker)
Host OS: Ubuntu 18.04 x84_64
Guest OS: macOS 10.14.2
USB device: iPhone 8 with iOS 12.1.2
When I connect a iPhone 6s with iOS 9, and no such problem.
Running MacOS on VMware Workstation via the "unlocker" hack tool is a violation of Apple's and VMware's EULA. You may only run MacOS on official Apple hardware. As a result, we cannot help you with your issues here.
