When I upgraded from nvda2022.4Beta3 to alpha-27213, I encountered a warning about a bad configuration file.

Steps to reproduce:

Upgrade NVDA from older version to alpha-27213,

Actual behavior:

I got a warning that my configuration is wrong and my configuration has been reset.
The specific error configuration is 'reportLineIndentation'.

Expected behavior:

We should have a solution that has the least impact on users.
Also, even if the configuration file is wrong, please help the user to keep the log containing the error instead of directly resetting to the default value.
