eGPU Disconnection issues in Mojave

Hi,

I am constantly having difficulities in disconnecting my eGPU from my laptop (Macbook Pro 13 inch 2017, Mojave).

It is a Blackmagic Radeon RX580 egpu, however the issue seems to be with OSX, not the peripheral.

95% of the time when I try to disconnect via the menu bar, it will fail and the laptop screen will go to a background only whilst the external monitor connected to the GPU displays as normal.

The only way out of this is to disconnect the eGPU from the thunderbolt cable, which results in OSX apparently crashing and landing me at the login screen, so if anything was unsaved prior to this, its gone.

Any help from apple support would be much appreciated, or is this a bug that needs to be fixed? Its an issue that really needs resolving, as if you are working from a laptop and are connecting and disconnecting to an egpu daily like myself, its quite a problem.

Any solutions from the community also would be greatly appreciated.

Thanks,

Matt.
