We removed Desktop testing in 10.x with the Selenium Upgrade and WinAppDriver didn’t work with Selenium 4.x.
I was able to bring it back using a different underlying technology but to justify the spend and the increased maintenance we had to move into the Enterprise license. You can pick up an Enterprise license on the pricing page for half off if you have 3 or less users.
