[asandikci]

• needs to be tested with NewPipe/Tubular to know if it is specific to this project

Steps to reproduce

• select a video from a channel group and start to play it
• after open another channel group and refresh it (fetch latest videos)
• select a new(?) video from this group and add it to queue
• make currently playing video fullscreen (?)
• exit from fullscreen and back to main menu (while video still playing)
• app crash

Is anyone can reproduce this? It sometimes occurs sometimes not. Probably I miss a step.

And is there any similar error on NewPipe/Tubular?
