Thanks for reporting this issue. We reproduced this issue and sent the issue to the development team for investigation.
Here is an interim workaround:
1. Open the macOS Big Sur VM's Advanced Settings, enable "Remote display over VNC" checkbox, set a VNC password and a VNC port
2. From another physical Mac machine, activate Finder, select Go > Connect to Server menu, input the following to connect to the macOS Big Sur VM by VNC:
vnc://<the IP of the mac host where the macOS Big Sur VM is stored>:<VNC port set in step 1>
3. Click Connect button, when prompted for password, enter the VNC password set in step 1
