app = typer.Typer()


@app.command()
def create(username: str):
    print(f"Creating user: {username}")


@app.command()

ZeroDivisionError: division by zero

note that the width of the table for help is much higher than the width of stacktrace. The max width for stack trace is only 100, which is very small, making it very hard to read for many our use-cases.
Specifically, the discrepancy is caused by this:
the help formatting is here https://github.com/tiangolo/typer/blob/0.12.0/typer/core.py#L674-L678 which calls https://github.com/tiangolo/typer/blob/0.12.0/typer/rich_utils.py#L126-L144 which sets the width to https://github.com/tiangolo/typer/blob/0.12.0/typer/rich_utils.py#L70 which is wither TERMINAL_WIDTH env var or None, leaving the rich package to figure it out.
While in the exception hook, the https://github.com/tiangolo/typer/blob/0.12.0/typer/main.py#L53-L102 is used which calls the rich from https://github.com/tiangolo/typer/blob/0.12.0/typer/main.py#L72-L79 and there it does not set the width so the default 100 is used, see https://github.com/Textualize/rich/blob/v13.7.1/rich/traceback.py#L245. And the console used by the the except hook is created in https://github.com/tiangolo/typer/blob/0.12.0/typer/main.py#L44 while it should instead obtain the rich console which contains the styling. This would make them more consistent.

This bug happens regardless of OS, although figuring out if the default showcase will be 80 or 100 is platform-dependent to some extent.
