Open vSwitch database connection failure

Question

I recently installed, open vswitch to use it in gns3 but when I open the console on solar PuTTY I get those errors:

2022-03-08T14:19:06Z|00001|fatal_signal|WARN|could not unlink "/var/run/openvswi tch/db.sock" (No such file or directory)

and when i tab "ovs-vsctl show" i get this error : ovs-vsctl: unix:/var/run/openvswitch/db.sock: database connection failed (No such file or directory)
