DEVICE-0202 Error while adding rSeries as a provider in CM

It sounds like there might be an issue with your Unity setup or permissions. Here are a few things you can try to fix it:

1. Run Unity as Administrator: Sometimes, Unity doesn't have the necessary permissions to create folders in certain directories. Right-click the Unity Editor icon and select "Run as administrator" to see if that helps.
2. Check Folder Permissions: Make sure the "Program Files" folder (C:/Program Files/Unity) has the correct write permissions. You can right-click the folder, go to "Properties," and check the permissions under the "Security" tab.
3. Try a Different Save Location: It's generally a good idea not to save Unity projects in the "Program Files" folder due to possible permission issues. Try creating the project in a different location, like your "Documents" or "Desktop" folder.
4. Check for Updates: Unity 2019.3.0a4 is an alpha version, which might have some bugs. You could try updating to a more stable version of Unity if possible.
5. Clear Cache: Sometimes, clearing the Unity cache can resolve unexpected issues. You can find cache and temporary files in the Unity folder in "AppData" (usually located at C:/Users/[Your Username]/AppData/Local/Unity).
