Bloom does not work in Build

i use bloom from the post processing stack in combination with HDR-Color / emission to add a glow effect to Images. This worked fine in 2018.3, but in 2019.1 it only works in the editor but not in the build (MacOS).

“… We successfully reproduced this issue and have sent it for resolution with our developers …”
