I think android is preventing the service from starting in the foreground. This could be due to a restriction imposed by the Android system or by the app itself.

Edit: When leaving Newpipe, Samsung kills the app when not using to improve battery life. See the reference here

Didn't think of the shitty OneUI app power management, but i'll definitely adjust the battery optimization settings for newpipe.
Though at some point (before this) I'd see a system pop-up telling me that the app isn't responding at random (I could be watching a video, or monitoring the downloads view and this would happen), then I knew if I were to swipe back, or tap back, the app will crash.

Same Issue here:

It was due to harsh battery optimizations in Samsung OneUI Device care App updates, but cannot verify if it still happens on user's device as user has deleted his account. I am using Samsung device on Android13, OneUI 5.1, Device Care version 13.6.07.4 & battery saver always ON , Battery set to optimized for NewPipe and found no problems in past months.

Hence Closing. If anyone faces issue having similar logs containing "Service startForeground not allowed due to mAllowStartForeground false" Can open a new issue please.

Reopening due to more reports of this issue in #12753 #12524 , but they lack steps of reproduction so let us reopen it.

@tct123 @VladaZemunac coming from your's respective issues #12753 #12524 please write your steps of reproduction here as asked in #12872 by dustdfg here specially the part "What did you do before crash occured? Even if you don't know what exactly lead to bug it would be helpful to know what you were doing"
