"Failed to launch checking" on Warmup Maximum Pairwise Product Fixing... subtasks

[alansegar]

Warmup Sum of Two Digits and Maximum Pairwise Product work as expected (Check button runs the tests and reports expected output).
But the following:

• Maximum Pairwise Product -- Fixing the Integer Overflow Issue
• Maximum Pairwise Product -- Fixing the Time Limit Issue
  result in X Incorrect Failed to launch checking despite Peek Solution showing that the code is identical to the solution.
  It's not possible to see the error detail in the Course view, just:

Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

For more on this, please refer to https://docs.gradle.org/8.8/userguide/command_line_interface.html#sec:command_line_warnings in the Gradle documentation.
