Hi all,
that app is a priviledged system app on the stock FP3 system and trying to get it to run is a lot of trouble.
I was able to half-way fix this on LineageOS by first uploading these blobs into the app’s own native libraries folder, named something like /data/app/com.android.fpcamera3-gXAqD9Yq5Z1FKG6CO0tFyA==/lib/arm64/. The lib/arm64 part of the path needs to be created first since it does not exist. After this, the app will start, but not run stably. I got a few pictures and videos, but it always ends up crashing sooner or later.
