This was working fine for me the other day, but today suddenly started crashing on startup. Tried a fresh install, no luck. I had been editing a custom script before opening, but undid the changes and also tried removing the script from the extensions folder but no luck there. The first crash was after opening a supertiled2unity prefab directly from my unity project.

Usually when an application crashes on macOS there is a crash dialog popping up, which could contain useful information about what triggers the crash. Do you see such a dialog?
Also, a fresh install does not reset your session or configuration. You could try deleting your `.tiled-session` file (stored alongside the project file) or resetting the settings by deleting `~/Library/Preferences/org.mapeditor.Tiled.plist`. However, please see if you can help find the cause of the crash before doing these steps (or, backup the files instead of deleting them, in case something in them can help reproduce the crash).

Hey, I tried both of these. It briefly solved the issue but it returned the next time I tried to open a file. I’m using SuperTiled2Unity as well, not sure if that could be causing issues.

That does look like a problem in Tiled. It’s crashing while trying to create a tab for a map that was open in your session.
Would it be possible to share your project, session and map / tilesets? In case you can’t share them on the forum, you could email them or send me a link? That way I could try to reproduce the problem, since from the stack trace I can’t make out what’s going wrong.
Also, it could help if you would test whether this problem still occurs in the current development version. If you log in to GitHub, you can visit [Python plugin: Added forgotten PyConfig\_Clear call · mapeditor/tiled@288cd98 · GitHub](https://github.com/mapeditor/tiled/actions/runs/8936731682) to find the latest build for macOS under “Artifacts”, take the “Tiled\_macOS-11+.app” and let me know whether that version is also crashing (and if so, post the report as done above).
