KLWP 3.78 - Broadcat/Flow stop working

Hello,
I use broadcast from Tasker and Niagara launcher to execute flows.
$br(tasker,animTasker)$
$br(niagara-launcher, screen)$

Everything works well and smooth with the 3.77 but it stops working with the 3.78. (after few minutes)
If I run the flow from a button, it works, so I imagine a problem with the broadcast.
I’m on S24 Ultra Android 15.
Thanks.
