I also experienced this issue, but waited a bit longer ... .
My version of VMware Workstation Pro is 15.0.0 build-10134415.
I found that the UI (vmware.exe) hung just after switching between tabs of my guests.
After a few forced shutdowns I decided to watch what was going on using
Process Explorer (procmon.exe).
The results showed that the UI was performing a directory scan of a new volume
that I had just mounted. This volume had 1,457,045 items occupying 2.29 TB
of space (you read that right).
After 8 or so hours the UI became responsive once more.
Hint to VMware developers and testers: check the scalability of your application
before shipping.
If you must perform a directory scan like this, try to move the callbacks onto
a thread other than the one(s) running a message loop.
Try looking at code around umi::dnd::CopyPaste::UpdateRemoteClipboard,
it may have something to do with this UI freeze.
