@asdffdsa is not referring to the output showed by RcloneBrowser, but the debug log you get when starting rclone in a terminal (Powershell) with the -vv option, e.g. like this
./rclone mount pcloud: Z: --vfs-cache-mode full --cache-dir "D:VFS Cache" -vv
RcloneBrowser is a tool that was built on top rclone and as such not really supported in this forum. Additionally the developer has put this on the RcloneBrowser project page:
WARNING: This project is not longer active or maintaned.
Initially I created it only because rclone mount did not work in the beginning. Now mount on Windows works fine, so this project is not useful for me anymore.
I suggest to try out rclone built-in web based GUI instead
I furthermore think I have solved your original issue with starting rclone as local user.
This will hopefully give you a nice ride without needing the RcloneBrowser
