#

this had happened to me before and i fixed it but forgot how i did irt

#

nevermind i think i fixed it???

#

i swear everytime i come here to make these posts my issue resolves itself

#

i ran sudo modprobe vhost_vsock which i saw somewhere which returned nothing but ran successfully

#

then i rebooted
