I'm generally experiencing no problems with Spine right now, but I have one file that Spine refuses to open - it crashes with an unexpected error every time. I've tried restoring earlier versions of the file - as far back as a month ago - and none of those will open either, so maybe this has something to do with a recent update? I was most recently editing this file on May 24 without any apparent issues.

Here's the log output after the crash:
