Hi,

  1. Create a new note with the following text:
    # Test
  2. Select either everything or everything but the number sign (the space must be selected).
  3. Press "Cut". The app should crash.

Nextcloud Notes 0.22
AnysoftKeyboard 1.9.2055
LineageOS 15.1 Android 8.1.0

Crashes on olders version of the app too (down to 0.14.2 at least, didn't try earlier than that).

Not reproducable by me. (pretty much the same setting).

Can you share the exact note content and the category and if it is marked as favorite, so i can set up the exact same environement?

The exact note is just # Test
Tried with no category and different categories and it crashes each time.
It also crashes whether the note is marked as favorite or not.

Can't reproduce, too.

I have been able to reproduce the issue on my physical device. I will try to investigate the behavior.

Is there any path forward without that RxMarkdown bug being fixed?

Here's another chunk to use....

Please have a look at #622.

TL;DR: I think i might have found a workaround which prevents the actual crash, but a complete fix is not possible for us until we have found and implemented another markdown rendering library.
