Problem with Parallel's Desktop and Big Sur

I installed the Big Sur Beta this afternoon on an iMac Pro. When I try to run Windows 10 or KDE Linux guest via Parallel's Desktop, I am unable to log in because not all keys are working. I thought it must have been a keyboard dust issue at first since it was so selective about keys, but those same keys work fine in Big Sur as a host. Most keys are working though.

I have tried to solve this by allowing Parallel's Desktop in Privacy and re-installing Parallel's Desktop.

Anyone else experiencing similar issues?
Sorry I have no resolution but I can confirm you are not the only one. Doesn't work for me either.
From Parallels site:

 5 - Cannot type certain symbols in VM (examples: 1, 2, T, Y, etc.)From the menu bar click Parallels Desktop icon (II) > Preferences > Shortcuts, then select the VM in question and click the plus button to create the corresponding shortcut for the necessary symbol. Repeat for each symbol that cannot be typed. 

Haven't test yet, had to change my windows password.
I had the same problem and implemented the solution from the Parallels site suggested by ThePrimate above. Worked for me.
