2. Deactivate CDPUserSvc
CDP or Connected Devices Platform is a service used to synchronize data such as Contacts, Mails, Calendar, OneDrive, etc. If you do not use many of these services, you can disable them.
Please note that this method requires you to make changes to Registry Editor settings. Serious problems can occur if you make changes to Registry Editor incorrectly. Please create a system restore point before continuing.
Launch the Run dialog box .
Type Regedit in the blank field of the box and press Enter to open Registry Editor.

In the Registry window that opens, navigate to the following path address:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CDPUserSvc
Switch to the right panel and double-click on the Start key to edit its value.

In the Edit String box that appears, change the number from the default value to 4 .
This will disable the service.
Now, close Registry Editor and exit.
Restart your PC to allow the changes to take effect.

New fix:
Yes, just go to App & Features->Cortana->Advanced Option->Reset. Try this method if you have popup message of Win32Bridge server error.
