Running NVDA 2023.3.4 or 2024.1 with --help or -h flags throws an error #16522

Closed Qchristensen closed 2 weeks ago

Qchristensen commented 3 weeks ago

Steps to reproduce:

Run either the launcher or an installed copy of NVDA 2023.3.4 or NVDA 2024.1 and including the latest alpha currently: alpha-31858,2d865027, with the --help command line argument, eg:

nvda_2024.1.exe --help

Actual behavior:

The following error message is displayed:

Errors in 'nvda.exe'

See the logfile 'C:\Users\quent\AppData\Roaming\nvda.log' for details

OK

(See log below)

Expected behavior:

NVDA should display the help screen of command line arguments etc, as earlier versions of NVDA display when using the --help argument.
