Hello guys, i am relatively new to Arch and after an Update some programms(VLC and Anki) are not running anymore. In both i get the error "Cannot mix incompatible Qt library (5.15.0) with this library (5.15.2)". Is there a way to solve this problem without downgrading qt, since i don't know if other programs depend on the newer version.

Check any unofficial (AUR or other) packages you have installed, they may need rebuilt. Especially themes.

As far as i know the only aur packages i've installed are android studio and ungoogled-chromium. I've rebuilt ungoogled-chromium already a few days ago and updated android studio. But it's not working. VLC and Anki are from the official repo since i've installed them with pacman.
Edit: with pacman -Qm i've found out that i've installed qt5-styleplugins from AUR. i rebuilt it and now everything is working fine.

Are you sure?
pacman -Qm
what's particularly often of interest here is qt5-styleplugins or so, which QT5 theme are you using.
