I have installed the last version 2.1.58 QT6 on Ubuntu 22.04 It is a new, fresh install, but hangs on startup when selecting profiles. Al so I tried 2.1.58 QT 5, but I then the menu was not sowed (and I repaired database) The command line shows this: $ anki Anki starting… Initial setup… Running with temporary Qt5 compatibility shims. Run with DISABLE\_QT5\_COMPAT=1 to confirm compatibility with Qt6. Preparing to run… Wayland support is disabled by default due to bugs: > > > \- \[x\] Qt 6.2.2, probably Qt5 too: editor sometimes pastes as text, sometimes pas…tes as html (mimeData.hasHtml() is returning intermittently false). Does not occur for me when using xwayland + QT\_QPA\_PLATFORM=xcb. Maybe related to https://bugreports.qt.io/browse/QTBUG-74330 (fixed in 6.3) > \- \[\] Qt 5/6.2.2/6.3: client side decorations are not supported, so when used on Gnome/Mutter, there are no borders/titlebars > \- \[x\] Qt 5/6.2.2: window.raise() is not supported, so clicking on 'add' to bring an existing add window to the top does not work (fixed in 6.3 for Sway, but not Gnome) > \- \[\] Qt 5/6.2.2/6.3: fullscreen mode renders Anki transparent (confirmed on 2.1.51 RC2, Manjaro Gnome; doesn't happen with Sway) > https://forums.ankiweb.net/t/blury-interface-with-gnome-wayland-and-fractional-scaling/19196/3?u=kleinerpirat > > Anki will link users to this page when they run Anki on a Wayland system.

Had been looking at this post trying to figure out what was going on since you tried both Qt6 and Qt5 with the recent screenshot, can only redirect for workarounds present in [Blank Main Window - Anki Manual](https://docs.ankiweb.net/platform/linux/blank-window.html) While you are in the manual, try others solutions/workarounds from 2.3.2-2.3.8 (left side) hopefully it can fix the issue, if not, we gotta wait for one of the devs or someone with experience on linux ---
