It doesn't provide crash report? If no could you achieve logcat output?

@dustdfg sorry if this is a newbie question but how may i get a logcat output?

@dustdfg sorry if this is a newbie question but how may i get a logcat output?

Well, it is not a newbie question actually... It requires adb usage and external computer (maybe can be done with local termux). Btw I asked just because you didn't provide any error message/dump and your description suggests that app crashes even before it can give you a proper error dump?

So you have an archive right...?

Can you try to delete the app and install again and import the archive without importing settings?

You say that main crash condition is amount of subscription. How many?

What version of newpipe was used to export archive? ( I mean you made an archive on x.xxx version and want to import it on 0.28.4 so what is x.xx.x?)

Newpipe archive management is not straightforward so there is an external app BendyStraw exactly for it. You can use it for two purposes:

1. Rescue your backup and etcc.
2. Make a copy of your archive and toy with it by cutting different parts from it and seeing if it starts to work when you import it

[Flam3z]

@dustdfg no error messages of any kind appeared at all. I have about 360 subscriptions and lastly the version I had used was its latest version to export the same way I had imported.

[Flam3z]

So after just importing everything but my settings the same issue occurs but now I have logs.
