IllegalStateException when removing FrameVideoView from the layout

[jauneshortcut]

I have a chat where I use FrameVideoView to animate the writing state of the chat bubble (three dots moving up and down). When I remove the FrameVideoView to replace it with the static text chat bubble, an IllegalStateException is thrown. Before I remove the FrameVideoView, I check that the mediaPlayer = null but when it comes toTextureViewImpl.release(), the MediaPlayer is not null and the exception is thrown.

Stack trace is the following:

Any suggestions how to make it work?
PS: it worked six months ago.
