systemctl and uwsgi issue for remote django app

Question

when I run uwsgi manually with uwsgi --ini uwsgi.ini command, it runs properly, but when I run sudo systemctl start uwsgi it will run properly (i.e., journalctl -b -u uwsgi or sudo systemctl status uwsgi won't show any errors) but I will get 500 error for all API calls. The errors do not happen when I run the server manually. And the uwsgi.service file worked fine until this morning so I don't know what is happening all of a sudden. help me please? The remote server is an ubuntu machine.

I tried relaxing the permissions of related files/directories etc, doesn't work. When I check the uwsgi log it says that django app was not found, but I'm pretty sure the env files/variables are correctly configured. It works fine when I run uwsgi manually too.

here is my uwsgi.ini file:

[uwsgi]
chdir = /home/ubuntu/"project_home"
module = "project_name".wsgi:application
home = /home/ubuntu/venv3.9
http = 0.0.0.0:8000
master = true
vacuum = true
# pidfile = /home/ubuntu/"project_home"/.config/uwsgi/uwsgi.pid
pidfile = /home/ubuntu/.uwsgi/uwsgi.pid
logto = /var/log/uwsgi:"my_project".log
for-readline = /home/ubuntu/"project_home"/.config/uwsgi/env
  env = %(_)
endfor =
uid = ubuntu
gid = www-data

here is my env file:

export DJANGO_SETTINGS_MODULE="my_project".settings.production
export DB_PASSWORD='password'
export EMAIL_HOST_PASSWORD='password_'
export SECRET_KEY="secret_key"

here is my uwsgi.service file:

[Unit]

Description=uWSGI Emperor service
After=syslog.target

[Service]
ExecStart=/home/ubuntu/venv3.9/bin/uwsgi --ini /home/ubuntu/"my_project"/.config/uwsgi/uwsgi.ini

RuntimeDirectory=uwsgi
Restart=on-failure

Just reiterating, when I run `

/home/ubuntu/venv3.9/bin/uwsgi --ini /home/ubuntu/"my_project"/.config/uwsgi/uwsgi.ini

manually, it works fine. the server works. but when I try to do that through systemctl it prints out the error that I copied to the first code block.
