Random crashes using Ctrl + X while multiple lines selected

[ArcMember]

Godot version

v4.1.1.stable.mono.official [bd6af8e]

System information

Windows 11 - Godot v4.1.stable - Vulkan (Forward+) - GeForce RTX 3060 Laptop GPU (nvidia, 536.67) - AMD Ryzen 7 5800H

Issue description

Godot crashes when using Ctrl+X (but not when using "Cut" from context menu) while cursor is on multiple lines (placed with Alt). Crashes are random because some lines are cut fine and only some cause crash with no obvious difference.

The only error in console:

Steps to reproduce

1. Write some code, I have consistent crashes on these lines:

var speed = max(1, speed_moving)
position += moving_vector.normalized() * speed * delta

2. Set cursros on both of them by pressing Alt + LMB
3. Press Ctrl+X

Minimal reproduction project

N/A

On it.

The copying operation itself works, the code gets to the end; it seems to crash later in the frame or something. 🤔

I can't see where this bug could be coming from.

Crash after setting cursors on 2 subsequent lines, here also with UI -> Edit -> Cut.
The error is IMO that it tries to delete 2 lines without a space between them..

ERROR: FATAL: Index p_index = 1 is out of bounds (size() = 0).

E.g. here it prints if the second caret is at the EOF position:

My crashes seem to be happening on any lines that are together, also happens on more than 2 lines.

This causes a crash

This does not cause a crash
