Hello community!
I’ve made a fix for the failed to open vchiq instance 
Here’s the instructions, just do what it tells you to do 
Systemd sevice unit (Step 1)
Save this file in: /etc/systemd/system
Name:permission.service
[Unit]
Description=Allow vchiq to be executed
[Service]
ExecStart=/usr/local/bin/permission.sh
[Install]
WantedBy=default.target
Startup shell script (Step 2)
Save this file in: /usr/local/bin
Name: permission.sh
#!bin/bash
cd /dev
sudo chmod 777 vchiq
Configure and Install (Step 3)
Go to the terminal and type the following:
sudo chmod 777 /usr/local/bin/permission.sh
sudo chmod 777 /etc/systemd/system/permission.service
sudo systemctl daemon-reload
cd /etc/systemd/system
sudo systemctl enable permission.service
sudo systemctl start permission.service
Hopefully this has helped you if you have this problem 
Goodbye for now.
