I have a directory Robot and have multiple suites (.robot files) in it. When i run individual file, tests run successfully. but when i run all suites together, the first .robot file run properly but from second file i get **No keyword with name ‘Open New Browser’ found.**  
command to run all suites under a folder:  
PycharmProjects/{projectname}/venv/bin/python -m robot -d Results --loglevel DEBUG -e EXCLUDED -i OUStests /Users/{user}/PycharmProjects/{projectname}/Tests/Web/Robot

I use robot framework with combination of python and selenium.  
RobotFramework==5.0  
Selenium==4.1.3  
robotframework-seleniumlibrary==6.0.0

these are my test setup and tear down:

## Test Setup run keywords Open New Browser Test Teardown run keywords Close All Browsers

my custom keywords file:

from SeleniumLibrary import \*  
from ..webdriver import WebDriver  
from robot.libraries.BuiltIn import BuiltIn

class CommonKeywords(SeleniumLibrary):  
@base.keyword  
def open\_new\_browser(self, alias=None):  
self.register\_driver(WebDriver().driver, alias=alias)

```
@base.keyword
def close_all_browsers(self):
    WebDriver().close()

```

my webdriver.py file:

from selenium.webdriver import DesiredCapabilities  
from .configuration import \*

from robot.libraries.BuiltIn import BuiltIn  
from selenium.webdriver.remote.command import Command

return None

        driver.set_window_size(1920, 1080)
        self.driver = driver
        BuiltIn().set_global_variable('${driver}', driver)
    else:
        self.driver = driver

def close(self):
    """Closes all open browsers and resets the browser cache.

            """
    self.driver.quit()
    BuiltIn().set_global_variable('${driver}', None)
