kandakchian I'm sorry to hear you're having trouble. I checked the attached spine.log file and it doesn't show what version of Spine Editor you are using, could you tell us that first? Also, the Spine Launcher you are using seems to be out of date, so please update it first. The log before the crash is a message about a missing key in a certain timeline, so it is probably a problem on the editor side, but updating the launcher version may make the log clearer.
To update your Spine launcher, please visit your license page and re-download the Spine installer and reinstall Spine using it.
