Seems to be related to missing Indirect Branch Tracking (IBT) Support of the VMNET module. This is enabled in Debian by default as of kernel 6.2 and will prevent Workstation 17.6.4 to run with network support.
Adding ibt=off to kernel parameters fixes this.
Please add IBT Support to the VMNET module!
Thank you!
Kind Regards.

Modules compile OK. However VMNET module can't be loaded. See Attachment.
In Order to load the VMMON Module i had to disable the Secure Boot feature in Bios.
The Notebook only has Wifi connection.
