Describe the bug
AmneziaVPN 4.8.15.4 fails to start on Linux Mint 22.3 XFCE (Ubuntu 24.04 base). Launching the binary gives an error: version 'Qt_6.10' not found in libQt6Core.so.6. The application appears to be compiled with Qt 6.10, but Ubuntu 24.04 LTS only provides Qt 6.4.2.

To Reproduce

Download AmneziaVPN_4.8.15.4_linux_x64.tar from the latest release.
Extract and run the installer: ./AmneziaVPN_Linux_Installer.bin
After installation, try to launch: /opt/AmneziaVPN/client/bin/AmneziaVPN
See error about missing Qt_6.10 version.

Expected behavior
The application should start normally on a supported distribution (Ubuntu 24.04 LTS) without manual Qt upgrades.

Log files

/opt/AmneziaVPN/client/bin/AmneziaVPN: /lib/x86_64-linux-gnu/libQt6Core.so.6: version `Qt_6.10' not found

/opt/AmneziaVPN/client/bin/AmneziaVPN: /lib/x86_64-linux-gnu/libQt6Qml.so.6: no version information available

Also version 4.8.12.9 fails with Qt_6.6 not found (requires Qt 6.6 but system has 6.4.2).

Desktop:

OS: Linux Mint 22.3 XFCE (based on Ubuntu 24.04 Noble)

Version: 4.8.15.4 (also tested 4.8.12.9)

Additional context

System Qt version: 6.4.2 (default for Ubuntu 24.04 LTS)

Installed dependencies as per docs: libxcb-cursor0 libxcb-xinerama0 libxcb-icccm4 libxcb-keysyms1 libopengl0

Also tried community-suggested Qt6 packages: libqt6core5compat6 libqt6quickcontrols2-6 libqt6remoteobjects6 libqt6svg6 + sudo ldconfig — no change.

The issue seems to be that the AmneziaVPN binary is linked against a newer Qt (6.10) than what Ubuntu 24.04 provides (6.4.2). Please either provide a build linked against Qt 6.4.2 or ship Qt libraries bundled with the application (AppImage/Flatpak).
