webcamoid has

Build-Depends: ..., qml6-module-qtquick-nativestyle, ...

but that package was removed in qt6-declarative/6.9.x, making webcamoid
unbuildable (an older "cruft" version is still available, but it depends
on a version of qt6-declarative-private-abi that is no longer available).

I encountered this while trying to rebuild-test the package with
libsdl2-dev provided by src:sdl2-compat from experimental, but it's
equally problematic in "pure" testing/unstable.

Please investigate whether this (build-)dependency can be removed.
