The error thrown here simply means that Jinja is unable to locate login.html. Ensure the templates/ folder contains the login.html file as the render_template(<path_to_file>) will look for it in the templates folder.

Note: Please do not share screenshots of code, rather snippets of code will help better.

To understand further and debug better: Flask raises TemplateNotFound error even though template file exists

Try using the --add-data flag to your pyinstaller command with the path to the templates folder as the argument.

For example:

pyinstaller --onefile --add-data "./templates;./templates" app.py

Use : as the path separator if you are using linux of mac.
