bug: ERA Viewer on Mac asks for the user's credentials every time the app is open

LOL, it's even worse! Both in 8.4.1 and 9.1.0 when I run ./era (in MacOS) I do get the NumberFormatException, but then after I log in it crashes:

Mar 12, 2026 2:57:00 AM com.sun.javafx.application.PlatformImpl startup
WARNING: Unsupported JavaFX configuration: classes were loaded from 'unnamed module @518e4625'
usage: EraDownloader
-a <arg> app id
-h display help message

Can it be worse? Yes it can! try: `./era -h` and you have to log in!

So basically era is not working on Mac from command line.

still not fixed in SDK 9.1.0

For me, the "Connect IQ Login" window that pops up after clicking on "Log In" hangs (shows spinner for ever).

So, I can't use SDK 8.4.1.   

If you run the era viewer from the command line, the following error message is displayed, which might be a clue:

❯ ./era
