After deploying the application created by Django to heroku, the application does not appear.

After deploying the application created by Django to heroku, the application does not appear.
After deployment, open the URL of the app
The following error occurred:

Application error
Error occurred in the application and your page could not be served. If you are the application owner, check your logs for details. You can do this from the Heroku CLI with the command
herokur logs --tail

When I checked that the log needs to be chucked
I found the following error, but I couldn't find a clear answer when I searched.
What is the possible cause of this error (at=error code=H10desc="App crashed"?
Also, I would appreciate it if you could advise me if there is a solution.

I think the error code you asked is either the application crashed or the startup timeout.
https://devcenter.heroku.com/articles/error-codes#h10-app-crashed

To run the app on Heroku

requirements.txt
Procfile
runtime.txt

The above three are required.Place everything in the root of the repository.

requirements.txt

 pip freeze>requirements.txt

For requirements.txt, execute the above command on the root of the repository.

Procfile

web:gunicorn myproject.wsgi

runtime.txt

 python-3.9.0

Please create and write the Procfile and runtime.txt files.
Change the Procfile myproject.wsgi to the project name.
The django development server is not suitable for the production environment, so we use gunicorn.
Before creating requirements.txt, run the following command:

 pip install gunicorn
