We noticed an issue with huge keyboard delay/wrong keys with VMWare Client 5.4.2, 5.4.3, 2006 build 8.0.0.
During our test, we noticed that issue most probably is caused by the latest Windows Update: KB4574727
Updates to improve security when using input devices (such as a mouse, keyboard, or pen).

During our test, the issue was solved as soon as we uninstalled the above update.
We are planning to collect logs and escalate it to the VMware, before that anyone any ideas ?
