Solution 2: Check if it is in Safe mode
Safe mode is also called safe boot. This mode helps to prevent some software from automatically loading or opening.
If the remote desktop issues still persist try to resolve it by checking if it is in safe mode.
After testing Remote Desktop is in Safe mode, try to restart it as in a normal way. Create a new user and see if the system is user specific or system wide.
You can also test if this issue happens to occur in another user account on Mac.
The above-given steps will help to resolve the remote desktop issue.
