Bug description

Seeing as all pre-built versions fail to even launch, I finally managed to build gridplayer using poetry with uv venv -p 3.10. But when running gridplayer, I only get audio playback, no matter what video decoding option or how many videos-per-process are chosen. And even then, the audio keeps playing after I've closed the file or the gridplayer window itself. There doesn't seem to be any relevant error/warning outputs from the Konsole. Just the annyoing Qt message: | QT | warning | Wayland does not support QWindow::requestActivate()

Log excerpt

Same for me, CashyOS too and Flatpak.
I can't use strace inside, but I can get more info: after few seconds (about 1 minute) trying to "prepare video output", app crash:

Should be working OK now. Flatpak package is updated and all Python versions are supported now as of latest commit, so you can install it using uv without specifying Python version.

uv tool install git+https://github.com/vzhd1701/gridplayer
