Navigate app in development mode first

How can I use the app in development mode first
I have issues concerning .env file.

Pre-Flight check messages:
1.Config file: We cannot determine if your config file is exposed to the outside world, so you will have to manually verify this. You don't ever want anyone able to see that file. Ever. Ever ever. An exposed .env file can disclose sensitive data about your system and database.

2.Environment: Your app is set local instead of production mode. If you're not planning on developing on Snipe-IT, please update your APP_ENV settings in your .env file to production.

also database error message
[16:27:56] LOG.debug: ErrorException: Attempt to read property "show_archived_in_list" on null

[snipe]

APP_DEBUG=true puts it in development mode. show_archived_in_list issue is already fixed via #16865
