[BUG] App freezes after repeatedly clicking "Upload a sprite style archive" (macOS)

[univeous]

Describe the bug
If you repeatedly click the "upload a sprite style archive" button, the application eventually freezes and becomes unresponsive. This happens regardless of whether you actually select a file or just press Esc to cancel the dialog.

To Reproduce
Steps to reproduce the behavior:

1. Go to the main screen where the "upload a sprite style archive" button is available.
2. Click the "upload a sprite style archive" button.
3. In the file dialog, either select a file or simply press Esc to cancel.
4. Repeat steps 2–3 several times (usually after a few attempts).
5. See error: the application freezes and does not respond to further input.

Expected behavior
The application should remain responsive no matter how many times the "upload a sprite style archive" button is clicked, even if the file dialog is cancelled multiple times.

Screenshots
n/a

Desktop (please complete the following information):

• OS: macOS Sonoma 14.5
• Version 1.2.0

Additional context

• This issue occurs even if you do not select any file and just cancel the dialog each time.
• This problem does not seem to occur on Windows; the app remains responsive there.
• If the app is started from the terminal, there is no log output when the freeze occurs—the terminal remains silent.

The same thing happens with the "load from json" button.

Thanks for reporting this. Full disclosure: I don't have a Mac to test the macOS builds on. I build the macOS build and perform what tests I can on a virtual machine. I will attempt to debug and patch this in the next couple of weeks. When I do, can I send you test builds to run on your machine? @univeous

Sure. I'd be happy to test it :)

Ran into this myself today. :(

Just wanted to pop in here and say this also happens on the Export screen. I think there is a bug with the Sprite Style selection. Once you've selected an sprite style, you can't trigger a file dialog again.

1. Start up the app, choose a Sprite Style with the "+"
2. Set up your sprite
3. Click through Configure into Export
4. Click to Choose a folder to export to.

My work around is to start the app and go to export first, choose the export folder, then back up to the main screen and add your sprite style now.

@DrieStone Are you experiencing this on v1.3.0? And are you also running macOS?
