Code Review
This pull request adds a complete Pong game implementation as a SweepMe! custom function. The code is well-structured with a Main class for integration and a PongWidget for the game itself. My review focuses on improving robustness, consistency, and maintainability. Key findings include overly broad exception handling that can hide bugs, inconsistencies in how configuration parameters like paddle sizes are handled between the Main class and the PongWidget, a potential crash in the configure method, and some dead code. I've also included suggestions to align with Python best practices like moving imports and removing magic numbers.

The configure method directly accesses self.widget without checking if it has been initialized. If configure is called before renew_widget, this will raise an AttributeError. You should add a guard to ensure self.widget is not None before accessing its attributes, for example by wrapping these lines in an if self.widget: block.

The paddle sizes are hardcoded to 50, ignoring the default values defined in the arguments dictionary. This can lead to unexpected behavior where the UI shows one value but the game uses another on startup. You should initialize self.paddle1_size and self.paddle2_size using the values from self.arguments.

This large try...except Exception: pass block, along with several nested ones, silently swallows all errors that might occur when updating the widget. This makes debugging extremely difficult as any issue (e.g., AttributeError, TypeError, ValueError) will be hidden. It's better to handle specific exceptions where they can be recovered from, or at least log the exceptions to aid in debugging.

The code to recenter the paddles after their size is updated is commented out. This means that if the paddle sizes are changed during runtime, they will not be recentered horizontally, which is a bug. You should uncomment these lines to ensure paddles are correctly positioned after a size change.

The method apply_updates_and_resume appears to be unused. Additionally, the attribute self.waiting_for_resume set on line 207 is not defined or used anywhere else. This suggests it is dead code. Unused code should be removed to improve maintainability.

The arguments dictionary defines "Paddle size", but the script.main method expects "Paddle 1 size" and "Paddle 2 size". When script.main is called, it will not find these keys and will fall back to the default values from Main.__init__, not the intended 120. This will cause the test script to run with unexpected paddle sizes. You should update the arguments dictionary to use the correct keys. This is also related to the PongWidget only accepting a single paddle_size on initialization.

The main method uses a hardcoded default value of "1" for new_ball_speed when calling kwargs.get(). This is inconsistent with the default value of "5.0" defined in the arguments dictionary and initialized in __init__. It's better to use the currently configured ball speed (self.ball_speed) as the default value to avoid unexpected speed changes.

According to PEP 8, Python's style guide, all imports should be at the top of the file, just after any module comments and docstrings. Moving these PySide2 imports to the top will improve code organization and adherence to standard Python conventions.

The PongWidget's __init__ method accepts a single paddle_size parameter, which is then used for both paddles. However, the Main class and other parts of the code are designed to handle separate sizes for each paddle (paddle1_size and paddle2_size). To make the component more flexible and consistent with the rest of the application, consider updating the __init__ method to accept separate sizes for each paddle. You will also need to update the method body to store and use these separate sizes.

The paddle speed is hardcoded as a magic number 8. It's better to define this as a constant at the class level (e.g., PADDLE_SPEED = 8). This improves readability and makes it easier to change the value in one place if needed.
