Hi,

SoulseekQt suddenly stopped working this morning on my Mac (no system update, no config change).
The app launches, appears in the dock, but never opens the main window and stays at 100% CPU indefinitely. It worked perfectly yesterday.

I tried:

Full reinstall of the latest version
Removing all related folders from ~/Library/Application Support, ~/Library/Preferences, ~/Library/Caches, ~/Library/Containers, and ~/Library/Saved Application State
Rebooting and testing from a clean user profile

Same result every time.
The crash report shows the process looping in
DataSaver::loadFromFile() → TransferQueueManager::OnDataLoaded().

System details:

macOS 26.0.1 (Sequoia)
Mac14,2 — Apple Silicon M2, 16 GB RAM
SoulseekQt 2024.6.30 (Qt 6.7.2, arm64e build)

Nicotine+ works fine on the same setup, so network and account are not the issue.
It seems like the app gets stuck while loading internal data.

Can you help me ?
Thanks

Hi Nicolas,

Can you please zip the contents of the .SoulseekQt folder in your home folder and send me the zip file via private email so I can try to reproduce the issue? I'll send you a private email to make sure you can respond directly to me.
