How do I debug MacVim crashing?

Steps to reproduce

I will be using macvim and maybe once every 2 days it will crash after hours and hours of use. Because of this time lag it's very difficult to run it in --clean mode, or to systematically eliminate plugins as sources of error.

Is there a crash log somewhere?

I looked in ~/Logs/... diagnostic reports (cant remember exact path) and there is nothing there

Expected behaviour

No crashing

Version of Vim and architecture

Latest MacVim

Environment

Latest iTerm, latest OSX, latest macvim, M2 CPU macbook pro

How MacVim was installed

brew install macvim

Vim configuration where issue is reproducable

No response

Issue has been tested with given configuration

• by running MacVim.app from GUI macOS interface
• by running vim/gvim/etc installed by MacVim
• by running other versions of vim (e.g. /usr/bin/vim)

Issue has been tested with no configuration

• by running mvim --clean (or gvim, supplied by MacVim distribution)
• by running vim --clean (in terminal, supplied by MacVim distribution)
• by running vim --clean (in terminal, other suppliers, e.g. /usr/bin/vim)

Other conditions

• The both Homebrew packages "vim" and "macvim" are installed

Start by reviewing the reported MacVim installation and environment, then compare MacVim.app with the terminal commands and clean-mode runs listed in the issue. Check the macOS diagnostic-report location and capture a crash log or a reproducible configuration; done means identifying a reproducible cause or obtaining actionable crash evidence.
