Does it appear when using nvim --clean? Is it relevant with nvimdots?

[qcmc17]

nvim --clean

i tried nvim --clean, works fine. maybe some plugins lead this problem

[ayamir]

Do you use nvimdots for root user?

[qcmc17]

You only provided stack backtrace for the main thread. What was the cause of this crash?

Can you provide the following extra debugging info (as much as possible):

Code Type (e.g., x86-64):

My suggestion is don't use root user to use this config. Maybe some plugins have conflict with root privilege.

[CharlesChiuGit]

Normally root user can only use default nvim/vim.

bad news, i tired build neovim from source with tag v0.8.3 and use nvimdots main branch on ubuntu22.04 for non-root user, but the coredump problems still exists，maybe u can reproducer the issues according to the above description.

Have you tried using the deb or Appimage provided by neovim releases?

[CharlesChiuGit]

Or just decompress the tar.gz file from the neovim repo?

I always use this on ubuntu22.04, never seen this error before.
