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, go to `Top menu → Hamburger menu → Help → Report a bug` and tap `Enable verbose logging`. Restart as requested, then repeat the steps for your issue.
