XFCE Desktop - trash, cannot execute file, command prompt here missing.

Hi there,

I am using the xfce4 is already the newest version (4.12.5) .
thunar is already the newest version (1.8.4-1) .
The distribution is Linux kali 4.19.0-kali1-amd64 #1 SMP Debian 4.19.13-1kali1 (2019-01-03) x86_64 GNU/Linux

However, the problem is:
When I when I click on any program to execute, it will show things like;

Failed to run "<insert program name here>"

Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

2ndly, when I right click, create document here, or create folder here, nothing shows up on the desktop itself.

Any help will be appreciate.

Maybe you can uninstall XFCE and reinstall it from the command line?

Have you ever had this problem with XFCE before?

Is that the original, verbatim error message that you see, or did you edit it?
Where does the error message stop? Looks like the consecutive sentences might belong to the message as well.
When did it occur, did it work before? What did you change?

For your second question, any log entries?
