Error in Gui

View attachment 13393

Hello people !!

I have this problem that happened out of nowhere, everything was working 100%, and it just happened, the strange thing is that the vms are all working fine, but I can not do anything for the GUI.
Hi,
did you touch the PATH variable of your system? Please post the output of echo $PATH.
 
This seems okay, and what about the permissions stat /usr/local/sbin /usr/local/bin /usr/sbin /usr/bin /sbin /bin
