You can upload the whole `crash.log` file (zipped if necessary) on GitHub by dragging and dropping it onto this textbox.
If your issue doesn't directly concern a Lua crash, we'll quite likely need you to reproduce the issue with *verbose* debug logging enabled before providing the logs to us.
To do so, from the file manager, go to [Tools] → More tools → Developer options, and tick both `Enable debug logging` and `Enable verbose debug logging`.
