I've been having the same issue where my Ubuntu MATE 22.04 guest VM constantly freezes. This is on a Windows 21H2 (OS Build 19044.2006) host, with VM Workstation 16.2.4 build-20089737. This happens regardless of the activity of the Guest VM, e.g. it even freezes when left idle after boot. This started a few weeks back after I had a few Windows updates forced onto me (corporate laptop...).
I let the guest sit idle except for a Clock running, to try to identify when the VM started to hang. And after about 20 minutes, I was not able to interact with the VM anymore. The VMWare log file contains around the time of the hang:

Something more weird is that there does seem to be some activity inside the guest VM. I have seen it update the time in the Clock application that I have open at least once. But I can't interact with the VM at all. Unfortunately, I only have a NAT network interface configured on the VM, so I can't check if it responds to network traffic. I doubt it though...
FYI the openvm-tools are running inside the VM...
