Citrix receiver (1812, 4.19 no difference)
Vmware 11.0.2 (latest)
macOS Mojave (latest)
Running Outlook in Citrix causes VMware to crash.
How to fix? I cannot get my work done...
Any reason you have the hypervisor enabled?
Also what do you mean by that, is that Hyper-V role enabled and/or the setting "Enable Hypervisor applications" of the VM hardware under menu Virtual Machine -> Settings -> Processor & Memory ?
From what I see you do not need it for Citrix Receiver, but you might require it for other reasons.
A thing you can try is to disable 3D in the virtual machine hardware.
Are you using unity?
edit: I read elsewhere that you enabled this feature in order to try and resolve the problem with Citrix Receiver. That's not what this option is for, it is best to leave it unchecked unless you want to run Hyper-V or another hypervisor within the guest. Try disabling 3D (settings -> Display) and see if that helps.
