I use Workstation Pro 16.0 every day on a Pop!_OS 20.10 host (similar to Ubuntu).  Yesterday when I tried to launch Workstation Pro 16.0, I got a "VMware Kernal  Module Updater" window stating "Before you can run VMware, sever modules must be compiled and loaded into the running kernal.".

Then another window with a red exclamation mark appears stating:

Unable to install all modules. See log /tmp/vmware-drk/-vmware4287.log for details. (Exit code 1)

It was working fine the previous day. I'm not sure what happened. I did have a minor OS update but I get those 2-3 times per week. I was worried about something like this happening when I upgraded from Pop OS 20.0 to 20.1 but i wouldn't have thought a minor OS update would cause this.
