I don't know RconeBrowser and is unable to spot the issue from the 2 screen shots.
Your mount options looks correct to me, but rclone apparently complains about the the (wrong/misplaced) parameter "Cache\"" which I cannot see in the screen shots. It could be an issue with the way RcloneBrowser passes quoted parameters to rclone. It would perhaps be possible to spot/explain/workaround the issue if we could see the full rclone command issued by the RcloneBrowser, but it may require some trial and error.
I therefore think we will be better able to help you if you execute your rclone commands directly from PowerShell and responded to your previous thread to see if we can easily get you into a non-Admin PowerShell.
