bug: E11: Invalid in command-line window; <CR> executes, CTRL-C quits

[FelipeLema]

Neovim version (nvim -v)

v0.11.4

Operating system/version

Windows 11

Describe the bug

on_complete_dispose triggers nvim_buf_delete and when the latter happens while user is in cmd / command line, it will trigger the error in the title.

Same as stevearc/oil.nvim#390 ... from the looks of it, would have to defer deletion to "later" (re-do defer_fn or create an au command for CmdlineLeave or something)

What is the severity of this bug?

tolerable (can work around it)

Steps To Reproduce

• Run a task with default parameters
• Type : to enter cmd line
• Wait until task is disposed of
• E11 is triggered

Expected Behavior

no error (printed) after task is disposed of

Minimal example file

No response

Minimal init.lua

Additional context

No response

I recently updated the buffer delete logic to be more graceful if it fails (using pcall for the nvim_buf_delete call). Can you see if that fixes the issue for you?
