Report generation hangs

[sternkern]

Hi!

I have recently faced an issue with the HTML reporter, hanging at the end of the session.
I am running Cucumber (9.1.2) in a NodeJS18/Typescript environment with the current test session size being around 300 test cases.
JSON and HTML reporting are enabled.

At the end of the session the failed TCs are listed, but it hangs before printing the line: X scenarios (Y failed, Z passed)

Executing some of the tests still generate the HTML report, only the full session breaks it.
I have checked for possibly invalid characters in the sentences, but found nothing.

Since it is company data I can not upload any complete logs, but let me know how I could debug the issue/add more logs.
Thanks!
