Activating the Clipboard History utility from within Parallels Toolbox rendered Microsoft Remote Desktop for Mac running workspaces almost useless, as it crashes continually when copying from within the RemoteApp streamed app. This can also hang local applications on the Mac until Remote Desktop has been force quit. We've replicated this on the original M1 13" MacBook Pro, an M1 Pro 14" and 16" MacBook Pro. Quitting Clipboard History returns Remote Desktop to operating normally. We're still not convinced that having Parallels Toolbox running without Clipboard History is entirely blameless, but due to the productivity hit this has caused, we're playing safe and no longer running the Toolbox at all.
