📝 Describe the Bug

I am loading one PDF URL and while it is in a loading state, I press the device back button. And then reload the same URL and I am getting this crash. I am using Jetpack Compose PdfRendererViewCompose() to load the URL.

Hi Do you mind sending me your PDF url, if its not confidential.

This doesn't look like a particular PDF problem, you can check with any large PDF directly loading from the HTTP URL and while it is loading press the back button and load it again, that way you can reproduce the problem.

+1 , works fine on an higer end device i.e S21, crashes on lower end devices like Asus Zenfone Max Pro M1

Update: now it stopped happening. No code changes.
