Please Follow the following steps:
1. Press Win+I to open Settings. Select Privacy > Microphone and Make sure that “Allow apps to access your microphone” is set to the On position. Do the same for Camera.
2. If it does not, create a system restore point and then type ‘regedit.exe’ in the search box, right-click and select ‘Run as administrator’ option.
When the Registry Editor opens, navigate to the following address on your Windows x64:
HKEY_LOCAL_MACHINE/Software/WoW6432Node/Microsoft/WindowsMediaFoundation
Double-click the folder to expand its menu and go to the sub-tree below.
Select ‘Platform folder’. If the Platform Key is not available, right-click on WindowsMediaFoundation and select New option to create one.
Now, switch to the pane on the right-hand side and right click any empty area to create a new 32-bit DWORD.
Set the name of this 32-bit DWORD as EnableFrameServerMode.
When done, double-click the value ‘EnableFrameServerMode’, change its value data to 0, and click OK button to save changes.
Thats it. It may solve your Problem.
