With the current build of signal-desktop on the Manjaro mirrors build steps for the binary are missing to be able to open the sticker-creator. This results in a crash when the user tries to access the sticker creator since it’s not found.
A sugested fix could be seen here. On Arch this package is build using this PKGBUILD; PKGBUILD · sticker-creator · Arch Linux / Packaging / Packages / signal-desktop · GitLab
Could the Signal build please be fixed so that stickers packs can be created?
