Can't uninstall Deepin file manager from my manjaro

Hi everybody.
I can not uninstall deepin file manager, I had a Nautilius and just wnted to check deepin. Now I can’t uninstall it from pamac or terminal.

How are you trying to uninstall it?
How exactly are you prevented from it?

sudo pacman -Rs deepin-file-manager

And then? What happens?

What is the output ?
Do you try it without the -R"s"

thanks all, I find the way. If anyone has the same issue, just reinstall it, then reboot the system and then run'sudo pacman -Rs deepin-file-manager' command.
