4.19 can't build lighting if preview rendering is set to android, on any project

So I just came across this huge problem and I don’t know what to do.
The build option is greyed out if I select Android as preview rendering level, so when I build my game and open it on my device there is no light built.
I tried this even with the zen garden project made by epic and I just can’t click it.

I seriously need help with this, I cant downgrade the project to 4.18 (which does build), or most of my content will not work!
