    So this is what I can into today … upgraded to Fusion 11.5 and got the message that the vmmon module was the wrong version.
    This appears to be a kext issue.

    The solution I found, remove the kext and copy the kext from the VMWare Fusion application as a replacement:

    1. Close VMware Fusion
    2. Open the Terminal and execute:

    sudo rm -rf /System/Library/Extensions/vmmon.kext
    
    sudo cp -pR /Applications/VMware\ Fusion.app/Contents/Library/kexts/vmmon.kext /System/Library/Extensions/
    
    sudo kextutil /System/Library/Extensions/vmmon.kext

    3. Exit Terminal and open Fusion again

    Now … you may run into an error message with the last command.
    In that case you can try the following command, or like I had to do: reboot your Mac and try that last command again;

    sudo kextunload /System/Library/Extensions/vmmon.kext
