Original GitHub issue: https://github.com/amnezia-vpn/amnezia-client/issues/1220

App starts , shows "Preparing status", then freezes for second and crush without errors.

To Reproduce

Install AmneziaVPN 4.7.0.0 x64 for Windows
Set up self hosted vpn
UPD: Turn on autoconnect BEFORE update
Update AmneziaVPN to 4.8.2.3 (installer from Releases page)
Start app

Expected behavior
App starts and working normally.

Log files
AmneziaVPN.log

Desktop (please complete the following information):

OS: Windows 10 22H2
App version 4.8.2.3

Additional context
Previosly I used 4.7.0.0 with self-host server. Around week ago the application started to work unstably: sometimes it did not connect when the system started, and did not disconnect correctly (required a PC reboot to restore the network). Then I decided to update to a newer version hoping for a fix.
I installed 4.8.2.3. After app launching, I see "Preparing" status for 1-2 sec and it's crash, without any errors. The same behavior when I downgrade to 4.8.1.9. When I downgrade to 4.7.0.0, app starts normally.

UPD: Turning off autoconnect in the older version and then update works for me.
If I turning it on in newer version after successful first launch, it's breaks down again. I suppose, it's known bug for these versions/update from older versions, but it's still unpleasant.

Same here. Win11 and clean install of the 4.8.1.9.
The program has autorun and autoconnect enabled.
The program has 100% crash rate when I run it from taskbar.
And I have good successful rate by clicking on AmneziaVPN.exe.

Thanks, that's works for me. Updated initial issue for more clarity.

If that's the case, is there any way to make it start up and connect without manually clicking through the GUI? Does Amnezia have any command-line parameters?
