I'm currently experiencing this as well.
Spine Version 4.2.02 (4.2.02)
Mac OS Sonoma 14.1.2
On launch I receive a dialog:
Fatal error - Spine
Sorry, a fatal error has occurred.
Antivirus software may crash Spine. Please disable any antivirus software or safelist Spine.
I haven't made any changes to my system since I last successfully used the application.
I've reviewed the information on the Troubleshooting page, but haven't found a solution.
Deleting the user data folder
~/Library/Application Support/Spine/ has allowed the app to complete launch, but the crash is still occuring when I click Start. I've noticed that the crash also occurs when I quit Spine from the start screen. Re-installing the launcher and restarting my machine has made no difference.
I'm unable to attach my log file for some reason. The upload keeps failing. But I'm receiving the same SIGSEGV in CoreFoundation as abuki.
