如视频中所展示的，版本选择列表在选择并保存后并不消失，而是可以继续选择另一个，并且它的鼠标输入判定区域溢出到了它的下面，导致无法通过点「启动游戏」按钮使其消失，启动游戏按钮直接点不到了（

As the video recorded, version selection list / instance selection list doesn't disappear after select a instance, you can select multiple times and it will save multiple times, and the mouse input area is overflowed, severely out of the widget, overlapped the 'Launch Game' button making it is unreachable unless you make your way to close the selection list

环境信息 / Runtime Environment:
ArchLinux rolling, Xanmod kernel, RTX4060 Mobile with nvidia-dkms, X11, Gnome, liberica-jdk11-full, AMD Ryzen R9-8945H with latest microcode

启动器崩溃报告 / 启动器日志文件 | Launcher Crash Report / Launcher Log File

看起来没什么有效的信息
Seems to be no valuable information...

Reproduce the version or instance selection behavior shown in the attached video, including repeated saves and the overflowed mouse area blocking “Launch Game.” Start from the launcher UI navigation context shown in the log, which ends at LauncherSettingsPage, and verify that selecting and saving once closes the list, prevents duplicate saves, and leaves the launch button reachable.
