Running as a systemd service MAVProxy on nVidia jetson nano

Hello, dear friends. I was able to install blues on my jetson nano, but when setting up the system, I realized that I would need to autorun MAVProxy immediately when power was applied. I watched the video guide from
aka: Matchstick, and there was also a link to github:
Running as a systemd service, which tells you how to do everything. I did everything according to the instructions, but MAVProxy gives an error at startup.


[Unit]
Description=MAVProxy
After=network.target

[Service]
Environment=“HOME=/home/crabtus/”
ExecStart=/usr/local/bin/mavproxy.py --master=/dev/ttyTHS1 --baudrate 115200 --daemon
Restart=on-failure
WorkingDirectory=/home/crabtus/
StandardOutput=inherit
StandardError=inherit
Restart=always

[Install]
WantedBy=multi-user.target

It is my code

Can you help me with this? Thank you in advance!
